Use Properties of Logarithms to Expand the Logarithmic Expression as Much

Multiple Choice

Use properties of logarithms to expand the logarithmic expression as much as possible.
- $\log _ { 4 } \frac { \sqrt [ 7 ] { 9 } } { s ^ { 2 } r }$

A) $\frac { 1 } { 7 } \log _ { 4 } 9 - 2 \log _ { 4 } s - 2 \log _ { 4 } r$
B) $\frac { 1 } { 7 } \log _ { 4 } 9 - 2 \log _ { 4 } s - \log _ { 4 } r$
C) $7 \log _ { 4 } 9 - 2 \log _ { 4 } s - \log _ { 4 } 7$
D) $\log _ { 4 } 9 - \log _ { 4 } s - \log _ { 4 } r$
