Express as the Logarithm of a Single Expression $3 \log _ { 5 } x + \frac { 1 } { 6 } \log _ { 5 } x - 2 \log _ { 5 } ( x + 1 )$

Multiple Choice

Express as the logarithm of a single expression. Assume that variables represent positive numbers.
- $3 \log _ { 5 } x + \frac { 1 } { 6 } \log _ { 5 } x - 2 \log _ { 5 } ( x + 1 )$

A) $\log _ { 5 } \frac { x ^ { 19 / 6 } } { ( x + 1 ) ^ { 2 } }$

B) $\frac { 19 } { 6 } \log _ { 5 } \frac { x } { ( x + 1 ) ^ { 2 } }$

C) $\log _ { 5 } \left( \frac { \frac { 19 } { 6 } x } { 2 ( x + 1 ) } \right)$

D) $\log _ { 5 } \frac { x ^ { 19 / 6 } } { 2 ( x + 1 ) }$
