Step 1.3.1

Reorder $\ln (z)$ and $\frac{1}{2}$ .

$1 + \ln (x^{3}) - \ln (y^{4}) - (\frac{1}{2} \ln (z))$

Step 1.3.2

Simplify $\frac{1}{2} \ln (z)$ by moving $\frac{1}{2}$ inside the logarithm.

$1 + \ln (x^{3}) - \ln (y^{4}) - \ln (z^{\frac{1}{2}})$

Step 2

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

$1 + \ln (\frac{x^{3}}{y^{4}}) - \ln (z^{\frac{1}{2}})$

Step 3

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

$1 + \ln (\frac{\frac{x^{3}}{y^{4}}}{z^{\frac{1}{2}}})$
