Step 1.2.1

Reorder $\ln (y)$ and $\frac{1}{8}$ .

$\ln (x^{9}) - (\frac{1}{8} \ln (y))$

Step 1.2.2

Simplify $\frac{1}{8} \ln (y)$ by moving $\frac{1}{8}$ inside the logarithm.

$\ln (x^{9}) - \ln (y^{\frac{1}{8}})$

Step 2

Use the quotient property of logarithms, $\log_{b} (x) - \log_{b} (y) = \log_{b} (\frac{x}{y})$ .

$\ln (\frac{x^{9}}{y^{\frac{1}{8}}})$
