Best Answer

A perfect square is the square of an integer, i.e., an integer multiplied by itself. For example, 25 is a perfect square, because 5 x 5 = 25.

But, in literal mathematical terms, a perfect number is a positive integer that is the sum of its proper positive divisors, excluding the number itself. A square number is also called a "perfect square", so an example of a square number is above.

So, a perfect square number would have to be a number that is both perfect and square, and there are yet to be any of these numbers "discovered".
