1) SQUARE ROOT BY PRIME FACTORISATION METHOD:-
>>To find the square root of any number, we need to figure out whether the given number is a perfect square or imperfect square. If the number is a perfect square, such as 4, 9, 16, etc., then we can factorise the number by prime factorisation method. If the number is an imperfect square, such as 2, 3, 5, etc., then we have to use a long division method to find the root.
Example: Square of 7 = 7 x 7 = 72 = 49
The square root of 49, √49 = 7
2) SQUARE ROOT BY LONG DIVISION METHOD:-
>>Finding square roots for the imperfect numbers is a bit difficult but we can calculate using a long division method. This can be understood with the help of the example given below. Consider an example of finding the square root of 436.
