Square Root:

A square root, often written as √, is a number that tells how many times one needs to multiply itself to equal the real-number represented. A square root can also be defined as the inverse of taking the square (or the second power) of a number. 

In other words, the square root is the number that, when multiplied by itself, equals the given number. For example, the square root of 9 is 3 because 3 x 3 = 9.

Square roots can also be used to find the side of a square with an area equal to the given number.
