$- 4 \sqrt{4 n^{2}} \cdot (2 \sqrt{3 n})$

Step 1

Rewrite $4 n^{2}$ as ${(2 n)}^{2}$ .

$- 4 \sqrt{{(2 n)}^{2}} \cdot (2 \sqrt{3 n})$

Step 2

Pull terms out from under the radical, assuming positive real numbers.

$- 4 (2 n) \cdot (2 \sqrt{3 n})$

Step 3

Multiply $2$ by $- 4$ .

$- 8 n \cdot (2 \sqrt{3 n})$

Step 4

Multiply $2$ by $- 8$ .

$- 16 n \sqrt{3 n}$
