$s - 7 {(\sqrt{s})}^{2 + 7}$

Step 1

Add $2$ and $7$ .

$s - 7 {\sqrt{s}}^{9}$

Step 2

Rewrite ${\sqrt{s}}^{9}$ as $\sqrt{s^{9}}$ .

$s - 7 \sqrt{s^{9}}$

Step 3

Rewrite $s^{9}$ as ${(s^{4})}^{2} s$ .

Step 3.1

Factor out $s^{8}$ .

$s - 7 \sqrt{s^{8} s}$

Step 3.2

Rewrite $s^{8}$ as ${(s^{4})}^{2}$ .

$s - 7 \sqrt{{(s^{4})}^{2} s}$

$s - 7 \sqrt{{(s^{4})}^{2} s}$

Step 4

Pull terms out from under the radical.

$s - 7 s^{4} \sqrt{s}$
