Step 5.1

Factor $9$ out of $27$ .

$\sqrt{9 (3) x^{3} y^{3}}$

Step 5.2

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

$\sqrt{3^{2} \cdot 3 x^{3} y^{3}}$

Step 5.3

Factor out $x^{2}$ .

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

Step 5.4

Factor out $y^{2}$ .

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

Step 5.5

Move $x$ .

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

Step 5.6

Move $3$ .

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

Step 5.7

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

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

Step 5.8

Add parentheses.

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

Step 5.9

Add parentheses.

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

Step 6

Pull terms out from under the radical.

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