Step 1.1

Factor $16$ out of $32$ .

${\sqrt[4]{16 (2)}}^{2}$

Step 1.2

Rewrite $16$ as $2^{4}$ .

${\sqrt[4]{2^{4} \cdot 2}}^{2}$

Step 2

Pull terms out from under the radical.

${(| 2 | \sqrt[4]{2})}^{2}$

Step 3

The absolute value is the distance between a number and zero. The distance between $0$ and $2$ is $2$ .

${(2 \sqrt[4]{2})}^{2}$

Step 4

Apply the product rule to $2 \sqrt[4]{2}$ .

$2^{2} {\sqrt[4]{2}}^{2}$

Step 5

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

$4 {\sqrt[4]{2}}^{2}$

Step 6

Step 6.1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[4]{2}$ as $2^{\frac{1}{4}}$ .

$4 {(2^{\frac{1}{4}})}^{2}$

Step 6.2

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$4 \cdot 2^{\frac{1}{4} \cdot 2}$

Step 6.3

Combine $\frac{1}{4}$ and $2$ .

$4 \cdot 2^{\frac{2}{4}}$

Step 6.4

Cancel the common factor of $2$ and $4$ .
