Step 1.1

Factor $36$ out of $216$ .

$- 4 \sqrt{36 (6) x^{2} y^{2} z}$

Step 1.2

Rewrite $36$ as $6^{2}$ .

$- 4 \sqrt{6^{2} \cdot 6 x^{2} y^{2} z}$

Step 1.3

Move $6$ .

$- 4 \sqrt{6^{2} x^{2} y^{2} \cdot 6 z}$

Step 1.4

Rewrite $6^{2} x^{2} y^{2}$ as ${(6 x y)}^{2}$ .

$- 4 \sqrt{{(6 x y)}^{2} \cdot 6 z}$

Step 1.5

Add parentheses.

$- 4 \sqrt{{(6 x y)}^{2} \cdot (6 z)}$

Step 2

Pull terms out from under the radical.

$- 4 (6 x y \sqrt{6 z})$

Step 3
