Simplify - square root of 121x^4y^6z^8

$- \sqrt{121 x^{4} y^{6} z^{8}}$

Step 1

Rewrite $121 x^{4} y^{6} z^{8}$ as ${(11 x^{2} y^{3} z^{4})}^{2}$ .

$- \sqrt{{(11 x^{2} y^{3} z^{4})}^{2}}$

Step 2

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

$- (11 x^{2} y^{3} z^{4})$

Step 3

Multiply $11$ by $- 1$ .

$- 11 x^{2} y^{3} z^{4}$
