Question

Which is a perfect square?

Answer 1

Answer:

I believe it's 6^2.

Step-by-step explanation: 6^2 is the same as 6 times 6. Here's a tip, if you see a 2 as an exponent, you can also say x squared. X to the power of 2 is the same as x squared.

Answer 2

Answer:

$6^{2}$

Step-by-step explanation:

$6^{1}$ = 6        $\sqrt{6}$ = 2.45 (NOT a perfect square)

$6^{2}$ = 36      $\sqrt{36}$ = 6 (perfect square)

$6^{3}$ = 216     $\sqrt{216}$ = 14.7 (NOT a perfect square)

$6^{5}$ = 7776   $\sqrt{7776}$ = 88.18 (NOT a perfect square)

If the answer ends with a decimal, they are not perfect squares.
