$y^{\frac{1}{8}} \cdot y^{\frac{3}{4}}$

Step 1

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

$y^{\frac{1}{8} + \frac{3}{4}}$

Step 2

To write $\frac{3}{4}$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$y^{\frac{1}{8} + \frac{3}{4} \cdot \frac{2}{2}}$
