Express $\log b \left( \frac { x ^ { \frac { 1 } { 3 } } y ^ { \frac { 1 } { 6 } } } { z ^ { 9 } } \right)$

Short Answer

Express $\log b \left( \frac { x ^ { \frac { 1 } { 3 } } y ^ { \frac { 1 } { 6 } } } { z ^ { 9 } } \right)$ as the sum or difference of simpler logarithmic quantities. Assume that all variables represent positive real numbers.
