${(\sqrt{y^{\frac{1}{4}}})}^{8}$

Step 1

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

${(y^{\frac{\frac{1}{4}}{2}})}^{8}$

Step 2

Multiply the numerator by the reciprocal of the denominator.

${(y^{\frac{1}{4} \cdot \frac{1}{2}})}^{8}$

Step 3

Multiply $\frac{1}{4} \cdot \frac{1}{2}$ .
