Step 5.1.1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{s}$ as $s^{\frac{1}{2}}$ .

$| s^{3} | (s (s^{\frac{1}{2}} \sqrt[5]{s^{2}}))$

Step 5.1.2

Rewrite $s^{\frac{1}{2}}$ as $s^{\frac{5}{10}}$ .

$| s^{3} | (s (s^{\frac{5}{10}} \sqrt[5]{s^{2}}))$

Step 5.1.3

Rewrite $s^{\frac{5}{10}}$ as $\sqrt[10]{s^{5}}$ .

$| s^{3} | (s (\sqrt[10]{s^{5}} \sqrt[5]{s^{2}}))$

Step 5.1.4

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[5]{s^{2}}$ as $s^{\frac{2}{5}}$ .

$| s^{3} | (s (\sqrt[10]{s^{5}} s^{\frac{2}{5}}))$

Step 5.1.5

Rewrite $s^{\frac{2}{5}}$ as $s^{\frac{4}{10}}$ .

$| s^{3} | (s (\sqrt[10]{s^{5}} s^{\frac{4}{10}}))$

Step 5.1.6

Rewrite $s^{\frac{4}{10}}$ as $\sqrt[10]{s^{4}}$ .

$| s^{3} | (s (\sqrt[10]{s^{5}} \sqrt[10]{s^{4}}))$

Step 5.2

Combine using the product rule for radicals.

$| s^{3} | (s \sqrt[10]{s^{5} s^{4}})$
