$(\ln (x)) (- \frac{x^{- 8}}{8})$

Step 1

Rewrite using the commutative property of multiplication.

$- \ln (x) \frac{x^{- 8}}{8}$

Step 2

Move $x^{- 8}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$- \ln (x) \frac{1}{8 x^{8}}$

Step 3

Combine $\frac{1}{8 x^{8}}$ and $\ln (x)$ .

$- \frac{\ln (x)}{8 x^{8}}$
