Tap for more steps...

Step 1.1

Factor $4$ out of $28$ .

$\sqrt{4 (7) x^{3} y^{3}}$

Step 1.2

Rewrite $4$ as $2^{2}$ .

$\sqrt{2^{2} \cdot 7 x^{3} y^{3}}$

Step 1.3

Factor out $x^{2}$ .

$\sqrt{2^{2} \cdot 7 (x^{2} x) y^{3}}$

Step 1.4

Factor out $y^{2}$ .

$\sqrt{2^{2} \cdot 7 (x^{2} x) (y^{2} y)}$

Step 1.5

Move $x$ .

$\sqrt{2^{2} \cdot 7 (x^{2}) y^{2} x y}$

Step 1.6

Move $7$ .

$\sqrt{(2^{2} (x^{2})) y^{2} \cdot 7 x y}$

Step 1.7

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

$\sqrt{{(2 x y)}^{2} \cdot 7 x y}$

Step 1.8

Add parentheses.

$\sqrt{{(2 x y)}^{2} \cdot 7 (x y)}$

Step 1.9

Add parentheses.

$\sqrt{{(2 x y)}^{2} \cdot (7 x y)}$

Step 2

Pull terms out from under the radical.

$2 x y \sqrt{7 x y}$
