Multiple Choice

Write the logarithmic expression as a single logarithm with coefficient 1, and simplify as much as
possible.
- $$\log _ { 5 } x - 8 \log _ { 5 } y - 9 \log _ { 5 } z$$

A) $\log _ { 5 } \frac { x } { y ^ { 8 } z ^ { 9 } }$
B) $\log _ { 5 } \left( x - y ^ { 8 } - z ^ { 9 } \right)$
C) $\log _ { 5 } \frac { x } { 72 y z }$
D) $\log _ { 5 } ( x - 8 y - 9 z )$
