225 is a perfect squarebecause 225 = 15*15
Technically, every positive number is a square in the real number system, but I assume you mean perfect square. And yes, 225 is a perfect square. 152 = 225

152 = 225, and 162 = 256 So there can be no integer, k, such that k2 = 250 and that is what defines a perfect square.

1 is a perfect square. This is because the square of 1 is 1.
15 = 1252 + 20(1*5) = 125 + 100 = 225 or 15*15 = 15*10 + 10*15/2 = 150 + 75 = 225
The square root of 1/100 is 1/10 which is a perfect square but perfect square are usually integers.
