Step-by-step explanation:

REFERENCE:

- An Integer is simply a whole number.

- Here, you have square roots. "Perfect squares" are square roots in which the square root of the number is an integer , or whole number.

__________

The perfect squares up to 100 are:

√1= 1  ( 1x1=1)

√4= 2 (2x2=4) and so on

√9= 3

√16= 4

√25= 5

√36= 6

√49= 7

√64= 8

√81= 9

√100= 10

____________

Now let's look at the answer choices:

A. √3. This is not an integer because the square root of 3 is a long decimal, 1.73205081. That's not a whole number.√3 is not in the list of perfect squares

B. √6. Not an integer. the square root of 6 is 2.44948974278. √6  is not listed in the perfect squares

C. √15 is 3.87298334621, which is not an integer. Not listed in the perfect squares.

D. √36 IS an integer. The square root of 36 is 6, which is a whole number. √36 is also listed in the perfect squares list. I know the square root of 36 is 6 because 6x6=36.

Answer= D
