Step 1.3.1

Rewrite $9$ as $3^{2}$ .

$y z \sqrt{x z} + \sqrt{3^{2} x y^{2} z^{3}}$

Step 1.3.2

Factor out $z^{2}$ .

$y z \sqrt{x z} + \sqrt{3^{2} x y^{2} (z^{2} z)}$

Step 1.3.3

Move $x$ .

$y z \sqrt{x z} + \sqrt{3^{2} y^{2} z^{2} x z}$

Step 1.3.4

Rewrite $3^{2} y^{2} z^{2}$ as ${(3 y z)}^{2}$ .

$y z \sqrt{x z} + \sqrt{{(3 y z)}^{2} x z}$

Step 1.3.5

Add parentheses.

$y z \sqrt{x z} + \sqrt{{(3 y z)}^{2} (x z)}$

Step 1.4

Pull terms out from under the radical.

$y z \sqrt{x z} + 3 y z \sqrt{x z}$

Step 2

Add $y z \sqrt{x z}$ and $3 y z \sqrt{x z}$ .

$4 y z \sqrt{x z}$
