The square root of a number is the value of power 1/2 of that number. In other words, it is the number whose product by itself gives the original number. It is represented using the symbol '√ '. The square root symbol is called a radical, whereas the number under the square root symbol is called the radicand. To find the square root of a number, we...
This is a very simple method. We subtract the consecutive odd numbersfrom the number for which we are finding the square root, till we reach 0. The number of times we subtract is the square root of the given number. This method works only for perfect square numbers. Let us find the square root of 16 using this method. 1. 16 - 1 = 15 2. 15 - 3 =12 3...
Prime factorization of any number means to represent that number as a product of prime numbers. To find the square root of a given number through the prime factorizationmethod, we follow the steps given below: 1. Step 1: Divide the given number into its prime factors. 2. Step 2: Form pairs of factorssuch that both factors in each pair are equal. 3....
Estimation and approximation refer to a reasonable guess of the actual value to make calculations easier and more realistic. This method helps in estimating and approximating the square root of a given number. Let us use this method to find √15. Find the nearest perfect square number to 15. 9 and 16 are the perfect square numbers nearest to 15. We ...
Long division is a method for dividing large numbers into steps or parts, breaking the division problem into a sequence of easier steps. We can find the exact square root of any given number using this method. Let us understand the process of finding square root by the long divisionmethod with an example. Let us find the square root of 180. 1. Step...

The square root of a number a a, denoted \sqrt {a} a, is the number b b such that. b^ {2} = a\text { and }b\ge 0. b2 = a and b ≥ 0. The square root symbol " \sqrt {\ } " is also sometimes called a radical. The number or expression underneath the top line of the square root symbol is called the radicand.
