Square Root

A square root is a mathematical operation that, when applied to a non-negative real number, produces another non-negative real number that, when multiplied by itself, gives the original number as the result.

In simpler terms, if you have a non-negative real number "x," the square root of "x," denoted as √x, is a number "y" such that:

**y × y = x

**or

**√x = y
