Use Properties of Logarithms to Write Each Expression as a Sum

Multiple Choice

Use properties of logarithms to write each expression as a sum or difference of logarithms. Assume that variables represent positive real numbers.
- $\log _{7} \frac{\sqrt[9]{5}}{n^{2} m}$

A) $\frac{1}{9} \log _{7} 5-2 \log 7 n-2 \log 7 m$
B) $9 \log _{7} 5-2 \log 7 n-\log _{7} 8$
C) $\frac{1}{9} \log _{7} 5-2 \log 7 n-\log _{7} \mathrm{~m}$
D) $\log _{7} 5-\log 7 n-\log 7 m$
