$6 x \sqrt{3^{2} x^{3}}$

Step 1.2

Factor out $x^{2}$ .

$6 x \sqrt{3^{2} (x^{2} x)}$

Step 1.3

Rewrite $3^{2} x^{2}$ as ${(3 x)}^{2}$ .

$6 x \sqrt{{(3 x)}^{2} x}$

Step 2

Pull terms out from under the radical.

$6 x (| 3 x | \sqrt{x})$

Step 3

Remove non-negative terms from the absolute value.

$6 x (3 | x | \sqrt{x})$

Step 4
