Multiple Choice

Write the logarithmic expression as a single logarithm with coefficient 1, and simplify as much as
possible.
- $7 \log x - \frac { 1 } { 7 } \log y - \frac { 4 } { 7 } \log z$

A) $\log \left( x ^ { 7 } y \sqrt [ 7 ] { z ^ { 4 } } \right)$
B) $\frac { x ^ { 7 } } { \sqrt [ 7 ] { y z ^ { 4 } } }$
C) $\log \left( x ^ { 7 } \sqrt [ 7 ] { y z ^ { 4 } } \right)$
D) $\log \left( \frac { x ^ { 7 } } { \sqrt [ 7 ] { y z ^ { 4 } } } \right)$
