I NEED HELP RN PLEASEEEE ITS AN EMERGENCY!!

strojnjashka [21]

Answer:

The answer is C) $12\sqrt{2}$ .

Step-by-step explanation:

For a real number $a$ ,

$\sqrt{a} \cdot \sqrt{a} = a$ .

In other words, multiplying a square root by itself gets rid of the square root.

How does this rule apply here?

$24 = 2\times 12$ .

Similarly,

$\sqrt{24} = \sqrt{2}\times \sqrt{12}$ .

That is:

$\begin{aligned}\sqrt{24}\times \sqrt{12} &= (\sqrt{2}\times \sqrt{12}) \times \sqrt{12}\\&=\sqrt{2}\times (\sqrt{12}\times \sqrt{12}) && \begin{array}{l}\text{By the associative property}\\\text{of multiplication}\end{array}\\&=\sqrt{2} \times 12\\ &= 12\sqrt{2}\end{aligned}$ .
