Multiple Choice

Write the expression as the sum or difference of single logarithms.
- $\log _ { 9 } \left( \frac { 8 \sqrt { x } } { y } \right)$

• A) \(\log _ { 9 } 8 \cdot \frac { 1 } { 2 } \log _ { 9 } m \div \log _ { 9 } y\)
• B) \(\log _ { 9 } 8 + \frac { 1 } { 2 } \log _ { 9 } x - \log _ { 9 } y\)
• C) \(\log _ { 9 } ( 8 \sqrt { x } ) - \log _ { 9 } y\)
• D) \(\log _ { 9 } y - \log _ { 9 } 8 - \frac { 1 } { 2 } \log _ { 9 } x\)
