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

Step 1

Move $r^{- 1}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

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

Step 2

Multiply $r^{4}$ by $r$ by adding the exponents.

Step 2.2.1

Raise $r$ to the power of $1$ .

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

Step 2.2.2

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

$\frac{1}{4 r^{1 + 4}}$

Step 2.3

Add $1$ and $4$ .
