Multiple Choice

Express the given logarithm as a sum and/or difference of logarithms. Simplify, if possible. Assume that all variables represent positive real numbers.
- $\log _{5} \frac{11 \sqrt{x}}{y}$

A) $\log _{5} 11 \cdot \frac{1}{2} \log _{5} \mathrm{~m} \div \log _{5} \mathrm{y}$
B) $\log _{5} y-\log _{5} 11-\frac{1}{2} \log _{5} x$
C) $\log _{5}(11 \sqrt{x}) -\log _{5} y$
D) $\log _{5} 11+\frac{1}{2} \log _{5} x-\log _{5} y$
