Step 1.1

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

$m^{- \frac{5}{8} + \frac{3}{8}}$

Step 1.2

Combine the numerators over the common denominator.

$m^{\frac{- 5 + 3}{8}}$

Step 1.3

Add $- 5$ and $3$ .

Step 1.4.2.1

Factor $2$ out of $8$ .

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

Step 1.4.2.2

Cancel the common factor.

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

Step 1.4.2.3

Rewrite the expression.

$m^{\frac{- 1}{4}}$

Step 1.5

Move the negative in front of the fraction.

$m^{- \frac{1}{4}}$

Step 2

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{1}{m^{\frac{1}{4}}}$
