$3 x \sqrt{9 y} + 4 \sqrt{25 y}$

Step 1

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

$3 x \sqrt{3^{2} y} + 4 \sqrt{25 y}$

Step 2

Pull terms out from under the radical.

$3 x (3 \sqrt{y}) + 4 \sqrt{25 y}$

Step 3

Multiply $3$ by $3$ .

$9 x \sqrt{y} + 4 \sqrt{25 y}$

Step 4

Rewrite $25$ as $5^{2}$ .

$9 x \sqrt{y} + 4 \sqrt{5^{2} y}$

Step 5

Pull terms out from under the radical.

$9 x \sqrt{y} + 4 (5 \sqrt{y})$

Step 6

Multiply $5$ by $4$ .

$9 x \sqrt{y} + 20 \sqrt{y}$
