Write the Expression as a Single Logarithm with Coefficient 1 $\frac { 1 } { 2 } \log _ { 2 } x ^ { 4 } + \frac { 1 } { 4 } \log _ { 2 } x ^ { 4 } - \frac { 1 } { 6 } \log _ { 2 } x$

Multiple Choice

Write the expression as a single logarithm with coefficient 1. Assume all variables represent positive real numbers.
- $\frac { 1 } { 2 } \log _ { 2 } x ^ { 4 } + \frac { 1 } { 4 } \log _ { 2 } x ^ { 4 } - \frac { 1 } { 6 } \log _ { 2 } x$

A) $\log _ { 2 } \left( x ^ { 7 } \right)$
B) $\log _ { 2 } \left( x ^ { 17 / 6 } \right)$
C) $\frac { 7 } { 6 } \log _ { 2 } \left( x ^ { 8 } \right)$
D) $\log _ { 2 } \left( x ^ { 9 / 2 } \right)$
