From the following given options, option A is correct.

What is a perfect square?

A perfect square is a positive integer that is derived by the multiplication of another integer by itself. Let say we have an integer (a) and the multiplication of a by itself (a²) = b. Here, b is a perfect square.

In the given question, the value that is equal to 64 will be 8. This is because the square root of 64 is 8. Also 8² = 64.
