Question

What is the perfect square of 75?

Answer 1

The (perfect) square of 75 is 5625

Explanation:

The (perfect) square of `75` is `75^2 = 5625`

The inclusion of the word "perfect" adds nothing to this question.
`A` is the perfect square of `B` if `sqrt(A)` is exactly equal to `abs(B)`. Often when determining the square root of a number we can only achieve an approximation; the original value is not a "perfect" square. However, when we square a given (Rational) number the result will be exact value, so the square will be "perfect".
