which numbers are perfect squares? check all that apply. 1 2 16 18 32 44 94 100

Explanation:

Step1: Recall perfect - square definition

A perfect square is a number that can be written as the product of an integer multiplied by itself.

Step2: Check 1

$1 = 1\times1$, so 1 is a perfect square.

Step3: Check 2

There is no integer $n$ such that $n\times n=2$, so 2 is not a perfect square.

Step4: Check 16

$16 = 4\times4$, so 16 is a perfect square.

Step5: Check 18

There is no integer $n$ such that $n\times n = 18$, so 18 is not a perfect square.

Step6: Check 32

There is no integer $n$ such that $n\times n=32$, so 32 is not a perfect square.

Step7: Check 44

There is no integer $n$ such that $n\times n = 44$, so 44 is not a perfect square.

Step8: Check 94

There is no integer $n$ such that $n\times n=94$, so 94 is not a perfect square.

Step9: Check 100

$100 = 10\times10$, so 100 is a perfect square.

Answer:

1, 16, 100
