$- \sqrt{81 a^{16} b^{20} c^{12}}$

Step 1

Rewrite $81 a^{16} b^{20} c^{12}$ as ${(9 a^{8} b^{10} c^{6})}^{2}$ .

$- \sqrt{{(9 a^{8} b^{10} c^{6})}^{2}}$

Step 2

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

$- (9 a^{8} b^{10} c^{6})$

Step 3

Multiply $9$ by $- 1$ .

$- 9 a^{8} b^{10} c^{6}$
