Answer
$\ln{r} -\ln{3} - \ln{s}$
Work Step by Step
RECALL:
(1) $\ln{(PQ)} = \ln{P} + \ln{Q}$
(2) $\ln{(\frac{P}{Q})} = \ln{P} - \ln{Q}$
Use rule (2) above to obtain:
$=\ln{r} - \ln{3s}$
Use rule (1) above to obtain:
$=\ln{r} -(\ln{3} + \ln{s})$
Subtract each term of the binomial to obtain:
$=\ln{r} -\ln{3} - \ln{s}$
