Answer 2

Hi!

A perfect square is the product of when a whole number is multiplied by itself

Ex:

6 × 6 = 36, 36 is the perfect square.

The number that is being multiplied is the square root.

So to find the correct answer for this question, let's use the process of elimination.

100 = 10 × 10 so we can cross out 100

64 = 8 × 8 so we can cross out 64

25 = 5 × 5 so we can cross out 25

Now all we have left is 24, which is not a perfect square.

Answer: A. 24

Hope this helps :)
