Step-by-step explanation:

Perfect Squares and their Square Roots

Perfect Square:

Taking a positive integer and squaring it (multiplying it by itself) equals a perfect square.

Example:   3 x 3 = 9   Thus: 9 is a perfect square.

Taking the square root (principal square root) of that perfect square equals the original positive integer.

Example:   √ 9 = 3   Where: 3 is the original integer.

Note:   An integer has no fractional or decimal part, and thus a perfect square (which is also an integer) has no fractional or decimal part.
