No, 15 is not a perfect square.
For a number to be a perfect square, the number's square root has to be a whole number. 9 is a perfect square because its square root is a whole number, 3. If the square root of the number is a decimal, then it is not a perfect square. For example, 13 does not divide evenly so it not a perfect square.
200 is neither a perfect square nor a perfect cube. A perfect square is an integer that can be expressed as the square of another integer, and the prime factorization of 200 (2^3 × 5^2) does not allow for all exponents to be even. Similarly, for a perfect cube, the prime factorization requires all exponents to be multiples of three, which is also not the case for 200.

0, 1 and 64 are three numbers that qualify.
Ralph likes numbers that are perfect squares. 25, 400, and 144 are all perfect squares, as they can be expressed as the square of an integer (5^2, 20^2, 12^2). 200 is also a perfect square (14^2), which is why Ralph likes it.
