Answer:Square Root Formula
The square root formula of a number, x is given as,
√x = x1/2
Suppose, x is any number such that, x = y × y, the formula to calculate the square root of x will be,
√x = √(y × y) = y
where, y is the square root of any number x. This also means that if the value of y is an integer, then x would be a perfect square.
