Which numbers are perfect squares? Check all that apply.

Andrew [12]

A perfect square is a number made by squaring a whole number.

Since

$1^2=1;$
$4^2=16;$
$10^2=100,$

numbers 1, 16, 100 are perfect squares. You cannot find such whole number n, that

$2=n^2;$
$18=n^2;$
$32=n^2;$
$44=n^2;$
$94=n^2,$

therefore, numbers 2, 18, 32, 44, 94 are not perfect squares.

Answer: 1, 16, 100.
