Extramarks is a global educational technology firm that is one of the world’s fastest-growing. The corporation has a large presence in India, South Africa, Indonesia, and the Middle East. Their product variety is vast! Preschool through full K-12 coverage, as well as higher education and competitive tests, are all provided. They, for one, are dedicated to ensuring that this community of students continues to develop, prosper, and strive for academic excellence. 

The education system, which has become an indispensable aspect of a person’s life, has a wide range of consequences. Learning today does not take place just via books. Online learning has become a very effective and profitable means of learning as technology has advanced.

Extramarks, a Delhi-based organisation, has worked hard to give students a fantastic course to study, practise, and achieve academic achievement. This e-learning portal shows how technology can be used to make learning more convenient and effective. The Extramarks make each student’s learning experience unique. Some students prefer tactile learning, some prefer auditory learning, and others prefer visual learning. However, these many methods are only a portion of the whole learning process; revision is also necessary.

However, why should anyone rely on e-learning software when conventional learning techniques are still viable? However, the Extramarks will respond. Extramarks are they effective, and how do they differ from standard learning methods?

The 360-degree approach

The 360-degree method is a stringent strategy used by Extramarks. This method was formally implemented into the e-learning platform after researchers and academics discovered it to be incredibly beneficial. This method consists of three major steps: learn, practise, and test. Anyone who follows these three basic principles should be successful.

Mentoring through the internet

Despite being an online technique, it does not lag in providing the learner with a mentor. From elementary school through higher education, students have the option of seeking mentor guidance and addressing any problem or subject that they find difficult to manage from elementary school through higher education. As a result, even if the instructor is not physically there with the student, Extramarks act as a bridge between them.

Plan of study

It is common for a student to lose track of time and disrupt his or her study regimen due to extracurricular activities or other factors. Extramarks tackles this issue by integrating a scheduler, which prevents any study-related topic from slipping through the cracks and keeps the learner up to speed on it.

Examine their development.

A student understands the benefits and drawbacks of Extramarks’ online exam capabilities. He or she is permitted to grow in whatever area or issue where he or she falls short, which ultimately improves the person’s growth.

Learning Mathematics formulas can help students improve their final test, board exam, and other entrance exam outcomes. These Math equations also aid in fast study and help learners memorise information. When it comes to fractions and percentages, they are both interrelated. There are also connections between chapters, such as percentages and profit and loss, complex numbers, and the concepts of real numbers and exponents. It implies that if students grasp the formulas in one chapter, they will be able to understand the formulas in the next; this is how Maths formulas become significant to learn.

The Square Root Formula is a formula created through decades of research to help in the speedy resolution of issues. Straightforward arithmetic computations, such as addition and subtraction, are simple to do. When the Square Root Formula comes to algebraic expressions, geometry, and other fields, however, Square Root Formula is essential to simplify the method and save time. Students will not only acquire formulae for every topic at Extramarks, but they will also learn how to generate such equations. As a consequence, learners will not need to memorise formulas since they understand the rationale behind them.

Students’ Mathematical ability will increase when they employ the Square Root Formula to solve issues imaginatively. The Square Root Formula is presented alphabetically on the Extramarks for their convenience. As a consequence, formulas that need to be modified or referenced can be located easily.

Squaring an integer is the opposite of square-rooting it. The square of a number is the value acquired by multiplying the number by itself, whereas the Square Root Formula is derived by locating a number that, when squared, yields the original number. If a is the square root of ‘b,’ then an a× a = b. Because the square of every integer is always a positive number, every number has two square roots, one positive and one negative. For example, 2 and -2 are both square roots of 4. In most cases, however, only the positive value is expressed as the Square Root Formula.

What is Square Root?

The Square Root Formula is a value that, when multiplied by itself, yields the original number. The Square Root Formula is the opposite of squaring a number. As a result, squares and square roots are ideas that are connected.

If x is the square root of y, it is denoted as x=y, or the same equation can be expressed as x2 = √y. √ is the radical symbol used to symbolise the numerical root here. When a positive number is multiplied by itself, it represents the number’s square. The Square Root Formula is a positive number that yields the original value.

The Square Root Formula properties

The Square Root Formula has the following key properties:

A perfect square root exists if an integer is a perfect square number.

A number can have a square root if it finishes with an even number of zeros (0’s).

Students can multiply the two square root values. For instance, if 3 is multiplied by 2, the result should be 6.

When two identical square roots are multiplied, the outcome should be a radical number. It denotes that the outcome is a non-square root number. For example, when 7 is multiplied by 7, the result is 7.

Because the perfect square cannot be negative, the square root of any negative integer is not defined.

The perfect square root does not exist if an integer ends with 2, 3, 7, or 8 (in the unit digit).

If a number’s unit digit ends with 1, 4, 5, 6, or 9, it can have a perfect square root.

Square Root Definition

A number’s square root is that element of a number that, when multiplied by itself, yields the original number. Special exponents are squares and square roots. Think about the number 9. When 3 is multiplied by itself, the outcome is 9. This can be expressed as 3 ×3 or 32. The exponent in this case is 2, and students call it a square. When the exponent is 1/2, it refers to the Square Root Formula. √n = n1/2, for example, when n is a positive integer.

How to Find Square Root?

The Square Root Formula is quite simple to calculate the square root of a perfect square integer. Perfect squares are positive integers that can be written as the product of two numbers. In other terms, perfect squares are integers that are stated as the value of any integer’s power 2. To get the Square Root Formula of an integer, they can use one of four approaches, which are as follows:

Repeated Subtraction Method of Square Root

Square Root by Prime Factorization Method

Square Root by Estimation Method

Square Root by Long Division Method

The Square Root Formula should be noted that the first three procedures are handier for perfect squares, although the fourth approach, long division, can be used for any number, perfect square or not.

Repeated Subtraction Method of Square Root

This is a straightforward way. Students subtract the consecutive odd integers from the number whose square root they are calculating until they reach 0. The number of subtractions equals the square root of the provided integer. This approach is only applicable to perfect square numbers. Using the Square Root Formula, to get the square root of 16.

16 – 1 = 15

15 – 3 =12

12 – 5 = 7

7- 7 = 0 

Square Root by Prime Factorization Method

Any number can be prime factored, which means that it can be represented as a product of prime numbers. To get the square root of a given integer using the prime factorization method, perform these steps:

Step 1: Take the supplied number and divide it into its prime elements.

Step 2: Create pairings of related factors in which both elements are equal.

Step 3: Choose one of the factors from the pair.

Step 4: Determine the product of the elements obtained by selecting one from each pair.

Step 5: The square root of the provided integer is that product.

Square Root by Estimation Method

Estimation and approximation are terms used to describe a plausible estimation of the actual number to make computations easier and more realistic. This approach is useful for estimating and approximating the Square Root Formula of an integer. To apply this way calculate √15. Find the ideal square numbers that are closest to 15. The perfect square numbers closest to 15 are 9 and 16. One already knows that √16 = 4 and √9 = 3. This means that 15 falls between 3 and 4. Now they must determine if √15 is closer to 3 or 4. Consider the numbers 3.5 and 4. Because 3.52 = 12.25 and 42 = 16, Thus,√ 15 falls between 3.5 and 4 and is closer to the latter.

Square Root by Long Division Method

Long Division is a method for dividing big numbers into steps or parts, so reducing the division issue down into a series of simpler stages. Using this approach, one can discover the precise square root of any given integer.

Square Root Table

Numbers and their square roots are listed in the square root table. The Square Root Formula is also handy for finding the squares of integers. Here is a well-prepared square root table to assist students in better grasping the topic.

Square Root Formula

A number’s square root has an exponent of 1/2. To get the square root of a number, use the square root formula. Students are familiar with the exponent formula: n√x = x1/n. When n equals 2, they call it the Square Root Formula. They can get the  Square Root Formula using any of the preceding methods, such as prime factorization, long division, and so on. 91/2 = √9 = √(3×3) = 3. As a result, the Square Root Formula for calculating the square root of an integer is √x= x1/2.

How to Simplify Square Root?

Students need to discover the prime factorization of the given integer to simplify a square root. If a factor cannot be grouped, it should be represented with the square root symbol. The simplified Square Root Formula is √xy = (x y), where x and y are positive integers.

Square Root of a Negative Number

Because a square is either a positive number or zero, the square root of a negative number cannot be a real number. Complex numbers, on the other hand, have solutions to the Square Root Formula of a negative number. -x is: √(-x)= i√x is the primary square root. In this case, 1 is the square root of -1.

Square of a Number

The square of the base is any number raised to exponent two (y2). So, 52 or 25 is known as the square of 5, whereas 82 or 64 is known as the square of 8. Students can simply calculate the square of an integer by multiplying it twice. For instance, 52 = 5 5 = 25, and 82 = 8 8 = 64. The outcome of finding the square of a whole number is a perfect square. They have perfect squares such as 4, 9, 16, 25, 36, 49, 64, and so on. A number’s square is always a positive number.

How to Find the Square of a Number?

A number’s square can be obtained by multiplying it by itself. To get the square of a single-digit number, Students can use multiplication tables, however, for two or more two-digit numbers, they conduct multiplication of the number itself. 99 Equals 81, for example, where 81 is the square of 9. Likewise, 33 Equals 9, where 9 is the square of 3.

Squares and Square Roots

Squares and square roots have a very strong relationship since each is the inverse of the other. In other words, if x2 = y, then x equals y. The Square Root Formula is easily recalled as follows:

When they remove the word “square” from one side of the equation, they obtain the Square Root Formula on the other. For instance, 42 = 16 equals 4 = 16. This is frequently referred to as “taking the square root on both sides.”

When they eliminate the “square root” from one side of the equation, students obtain a square on the other. For example, √25 = 5 means that 25 = 52. This is sometimes referred to as “squaring on both sides.”

Square Root of Numbers

The product of multiplying an integer by itself is the square of that number. 6×6 equals 36, for example. In this case, 36 is the square of 6. A number’s square root is that component, and when multiplied by itself, the result is the original number. If students wish to discover the Square Root Formula of √36, which is 36, the answer is √36 = 6. As a result, they can observe that the Square Root Formula of a number is an inverse operation.

Examples on Square Root

Mathematics equations help learners solve complex problems rapidly. Learning new Math formulas is difficult for learners of all grades (6, 7, 8, 9, 10, 11, and 12). These learners simply need a few ideas and tactics to help them quickly understand these formulas. At this point, The Extramarks publishes a PDF of the Mathematical Formulas for CBSE students in grades 6 to 12, so that any student can quickly download the Basic Maths Formulas from the website and app.

Mathematics is a conceptual subject that requires a thorough understanding of all formulas. The Square Root Formula lets students use various strategies and tricks to solve complex problems. When students examine the Square Root Formula as fractions and percentages, they will notice that they are both interrelated. There are also connections between chapters, such as percentages and profit and loss, complex numbers, and the concepts of real numbers and exponents. The Square Root Formula indicates that if students understand the formulas in one chapter, they will be able to understand the formulas in the next; this is how Maths formulas become vital to learn.

Example questions based on the Square Root Formula must be solved. All types of Square Root Formula problems should be practised on a regular basis.Students are encouraged to tackle Square Root Formula questions using the Extramarks learning platform.
