Use Properties of Logarithms to Condense the Logarithmic Expression $$\frac { 1 } { 6 } ( \log 9 x + \log 9 y )$$

Multiple Choice

Use properties of logarithms to condense the logarithmic expression. Write the expression as a single logarithm
whose coefficient is 1. Where possible, evaluate logarithmic expressions.
- $$\frac { 1 } { 6 } ( \log 9 x + \log 9 y )$$

A) $\log 9 \sqrt [ 6 ] { x y }$
B) $\log _ { 9 } \sqrt [ 6 ] { x } + \log _ { 9 } \sqrt [ 6 ] { y }$
C) $\sqrt [ 6 ] { \log _ { 9 } ( x y ) }$
D) $\log _ { 9 } \sqrt [ 6 ] { x + y }$
