Multiple Choice

Write the expression as a single logarithm with coefficient 1. Assume all variables represent positive real numbers with $$a \neq 1 \text { and } b \neq 1$$
- $$\frac { 1 } { 3 } \log _ { 3 } \left( x ^ { 6 } \right) + \frac { 1 } { 6 } \log _ { 3 } \left( x ^ { 6 } \right) - \frac { 1 } { 9 } \log _ { 3 } x$$

A) $\log _ { 3 } \left( x ^ { 7 } \right)$
B) $\frac { 7 } { 9 } \log _ { 3 } \left( x ^ { 12 } \right)$
C) $\log _ { 3 } \left( x ^ { 26 / 9 } \right)$
D) $\log _ { 3 } \left( x ^ { 9 / 2 } \right)$
