Step 1.1.1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[3]{x}$ as $x^{\frac{1}{3}}$ .

$x^{\frac{1}{3}} \sqrt{2 x}$

Step 1.1.2

Rewrite $x^{\frac{1}{3}}$ as $x^{\frac{2}{6}}$ .

$x^{\frac{2}{6}} \sqrt{2 x}$

Step 1.1.3

Rewrite $x^{\frac{2}{6}}$ as $\sqrt[6]{x^{2}}$ .

$\sqrt[6]{x^{2}} \sqrt{2 x}$

Step 1.1.4

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

$\sqrt[6]{x^{2}} {(2 x)}^{\frac{1}{2}}$

Step 1.1.5

Rewrite ${(2 x)}^{\frac{1}{2}}$ as ${(2 x)}^{\frac{3}{6}}$ .

$\sqrt[6]{x^{2}} {(2 x)}^{\frac{3}{6}}$

Step 1.1.6

Rewrite ${(2 x)}^{\frac{3}{6}}$ as $\sqrt[6]{{(2 x)}^{3}}$ .

$\sqrt[6]{x^{2}} \sqrt[6]{{(2 x)}^{3}}$

Step 1.2

Combine using the product rule for radicals.

$\sqrt[6]{x^{2} {(2 x)}^{3}}$

Step 1.3

Apply the product rule to $2 x$ .

$\sqrt[6]{x^{2} \cdot 2^{3} x^{3}}$

Step 1.4

Multiply $x^{2}$ by $x^{3}$ by adding the exponents.

Step 1.4.1

Move $x^{3}$ .

$\sqrt[6]{x^{3} x^{2} \cdot 2^{3}}$

Step 1.4.2

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\sqrt[6]{x^{3 + 2} \cdot 2^{3}}$

Step 1.4.3

Add $3$ and $2$ .

$\sqrt[6]{x^{5} \cdot 2^{3}}$

Step 1.5

Raise $2$ to the power of $3$ .

$\sqrt[6]{x^{5} \cdot 8}$

Step 2

Reorder factors in $\sqrt[6]{x^{5} \cdot 8}$ .

$\sqrt[6]{8 x^{5}}$
