$3 \log (x) + \log (4) - \log (x) - \log (6)$

Step 1

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

$3 \log (x) + \log (\frac{4}{x}) - \log (6)$

Step 2

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

$3 \log (x) + \log (\frac{\frac{4}{x}}{6})$
