Use the Product, Quotient, and Power Rules of Logarithms to Rewrite

Multiple Choice

Use the product, quotient, and power rules of logarithms to rewrite the expression as a single logarithm. Assume that all
variables represent positive real numbers.
- $7 \ln ( x y ) - 3 \ln ( y z )$

A) $\frac { \ln \left( x ^ { 7 } y ^ { 7 } \right) } { \ln \left( y ^ { 3 } z ^ { 3 } \right) }$
B) $\ln \left( \frac { 7 x } { 3 z } \right)$
C) $\ln \left( \frac { x ^ { 7 } y ^ { 4 } } { z ^ { 3 } } \right)$
D) $\frac { \ln ( 7 x y ) } { \ln ( 3 y z ) }$
