Answer 1

Hey there :)

2 × √36

We know that 36 is a perfect square of 6
√36 = 6

Therefore 
$\boxed {2 \ times \ 6 }$ = 2 × 6 = 12

Your answer will be $\boxed {Option \ C }$

12² = 144 which means √144 = 12

Therefore: $\boxed {Option \ E \ is \ another \ answer }$

Answer 2

The correct options are C: 12 and E: $\sqrt{144}$

Explanation:
$2 \sqrt{36} \\ 2 \sqrt{6^2} \\ 2 * 6 = 12$

Now:
$\sqrt{144} \\ \sqrt{12^2} \\ =\ \textgreater \ 12$
