Hello @dontae_junoir and Welcome to OpenStudy! :)
here is the definition of a "perfect square"
http://www.mathsisfun.com/definitions/perfect-square.html
it is basically a number that comes from a whole number being multiplied by itself

for example: 4 x 4 = 16 therefore 16 is a perfect square
5 x 5 = 25 therefore 25 is a perfect square
and you can keep on going :)
6 x 6 = ?
7 x 7 = ?
8 x 8 = ?
9 x 9 = ?
you won't have to go too far before you get your answer!
try it out ^_^
