$- \sqrt{{(x^{2} - 6)}^{8}}$

Step 1

Rewrite ${(x^{2} - 6)}^{8}$ as ${({(x^{2} - 6)}^{4})}^{2}$ .

$- \sqrt{{({(x^{2} - 6)}^{4})}^{2}}$

Step 2

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

$- {(x^{2} - 6)}^{4}$

Step 3

Use the Binomial Theorem.

$- ({(x^{2})}^{4} + 4 {(x^{2})}^{3} \cdot - 6 + 6 {(x^{2})}^{2} {(- 6)}^{2} + 4 x^{2} {(- 6)}^{3} + {(- 6)}^{4})$
