about finding square root :-
mathematical operations have an inverse, or opposite, operation. Subtraction is the opposite of addition, division is the inverse of multiplication, and so on. Squaring, which we learned about in a previous lesson (exponents), has an inverse too, called "finding the square root." the square of a number is that number times itself. The perfect squares are the squares of the whole numbers: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100
how to find square root :-
example.Find the √2401
Solution:
➡Step1: Decide the unit’s place of the result.
2401 ends with 1 = Square root will end with 1 or 9
➡Step2: Leave the last 2 digits and find the immediate perfect square before the remaining number.
The immediate square before 24 = 16, which is 42
That is the number in ten’s place
41 or 49
➡Step 3: To determine whether the square root of 2401 is 41 or 49
To find the square root of a number we need to try to reduce the number into its perfect square factors
