Step 1.1

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

$\frac{m^{\frac{3}{4}}}{m^{\frac{5}{4} - 2}}$

Step 1.2

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

$\frac{m^{\frac{3}{4}}}{m^{\frac{5}{4} - 2 \cdot \frac{4}{4}}}$

Step 1.3

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

$\frac{m^{\frac{3}{4}}}{m^{\frac{5}{4} + \frac{- 2 \cdot 4}{4}}}$

Step 1.4

Combine the numerators over the common denominator.

$\frac{m^{\frac{3}{4}}}{m^{\frac{5 - 2 \cdot 4}{4}}}$
