ok explan to me why it isnt a perfect square (so i can under stand

OpenStudy (anonymous):

Of course, a perfect square is a number that can be square rooted and end up with a whole number. For example, 64. because if you square root 64 you get 8. Or 16, because 16 square rooted is 4. Do you get it now?
