Use the Product, Quotient, and Power Rules of Logarithms to Rewrite

Multiple Choice

Use the product, quotient, and power rules of logarithms to rewrite the expression as a single logarithm. Assume that all
variables represent positive real numbers.
- $\frac { 2 } { 7 } \log _ { a } x + \frac { 1 } { 5 } \log _ { a } y$

A) $\frac { 2 } { 35 } \log _ { a } x y$
B) $\log _ { a } \left( x ^ { 2 / 7 } y ^ { 1 / 5 } \right)$
C) $\log _ { a } \left( y ^ { 2 / 35 } \right)$
D) $\log _ { a } \left( x y ^ { 2 / 35 } \right)$
