Answer:
36, 16, 81, and 64.
Step-by-step explanation:
These numbers are perfect squares in that when you find the square root of that number it is a whole number. For example [tex]\sqrt{36}[/tex] = 6 because 6 × 6 =36.
72 is not a perfect square because [tex]\sqrt{72}[/tex] = 8.48528137424, which isn't a whole number.
