A perfect square is what u get when u multiply 2 of the same numbers together.
For example : 2 * 2 = 4.....4 is a perfect square
3 * 3 = 9...9 is a perfect square
4 * 4 = 16....16 is a perfect square
2 cannot be a perfect square because u cant multiply anything by itself that equals 2.
so ur perfect square numbers are : 1,4,9,25,36,81,144,225,400
