Step 1.1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[3]{2}$ as $2^{\frac{1}{3}}$ .

$2^{\frac{1}{3}} \sqrt[5]{3}$

Step 1.2

Rewrite $2^{\frac{1}{3}}$ as $2^{\frac{5}{15}}$ .

$2^{\frac{5}{15}} \sqrt[5]{3}$

Step 1.3

Rewrite $2^{\frac{5}{15}}$ as $\sqrt[15]{2^{5}}$ .

$\sqrt[15]{2^{5}} \sqrt[5]{3}$

Step 1.4

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[5]{3}$ as $3^{\frac{1}{5}}$ .

$\sqrt[15]{2^{5}} \cdot 3^{\frac{1}{5}}$

Step 1.5

Rewrite $3^{\frac{1}{5}}$ as $3^{\frac{3}{15}}$ .

$\sqrt[15]{2^{5}} \cdot 3^{\frac{3}{15}}$

Step 1.6

Rewrite $3^{\frac{3}{15}}$ as $\sqrt[15]{3^{3}}$ .

$\sqrt[15]{2^{5}} \sqrt[15]{3^{3}}$

Step 2

Combine using the product rule for radicals.

$\sqrt[15]{2^{5} \cdot 3^{3}}$

Step 3

Raise $2$ to the power of $5$ .

$\sqrt[15]{32 \cdot 3^{3}}$

Step 4

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

$\sqrt[15]{32 \cdot 27}$

Step 5

Multiply $32$ by $27$ .

$\sqrt[15]{864}$

Step 6

The result can be shown in multiple forms.

Exact Form:

$\sqrt[15]{864}$

Decimal Form:

$1.56952263 \dots$
