Answer 1

Answer:

$12\sqrt{7}$

Step-by-step explanation:

First, try to find any perfect squares in this. 9 is a perfect square, and 252/9 is 28.

$\sqrt{9 * 28}$

Now that we have this broken out, we can take the square root of 9 and take it outside the radical.

$3\sqrt{28}$

Are there any other perfect squares? 4 is a perfect square, and 28/4 is 7, so repeat the same step but with 4.

$3\sqrt{4 * 7}$

Then take the square root of 4 out of the radical and multiply it with the other number, 3.

$3 * 4\sqrt{7}$

$12\sqrt{7}$

This is your answer.
