$5 \sqrt{3 a^{2}} \cdot (3 \sqrt{25 a})$

Step 1

Reorder $3$ and $a^{2}$ .

$5 \sqrt{a^{2} \cdot 3} \cdot (3 \sqrt{25 a})$

Step 2

Pull terms out from under the radical.

$5 (a \sqrt{3}) \cdot (3 \sqrt{25 a})$

Step 3

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

$5 a \sqrt{3} \cdot (3 \sqrt{5^{2} a})$

Step 4

Pull terms out from under the radical.

$5 a \sqrt{3} \cdot (3 (5 \sqrt{a}))$

Step 5

Multiply $5$ by $3$ .

$5 a \sqrt{3} \cdot (15 \sqrt{a})$

Step 6

Multiply $5 a \sqrt{3} (15 \sqrt{a})$ .
