Write as the Sum And/or Difference of Logarithms $\log _ { 8 } \frac { 11 \sqrt { r } } { s }$

Multiple Choice

Write as the sum and/or difference of logarithms. Express powers as factors.
- $\log _ { 8 } \frac { 11 \sqrt { r } } { s }$

A) $\log _ { 8 } s - \log _ { 8 } 11 - \frac { 1 } { 2 } \log _ { 8 } r$
B) $\log _ { 8 } 11 + \frac { 1 } { 2 } \log _ { 8 } \mathrm { r } - \log _ { 8 } \mathrm {~s}$
C) $\log _ { 8 } ( 11 \sqrt { \mathrm { r } } ) - \log _ { 8 } \mathrm {~s}$
D) $\log _ { 8 } 11 \cdot \frac { 1 } { 2 } \log _ { 8 } \mathrm {~m} \div \log _ { 8 } \mathrm {~s}$
