Rewrite the Expression as the Sum And/or Difference of Logarithms $$\log _ { 17 } \frac { 5 \sqrt { x } } { y }$$

Rewrite the expression as the sum and/or difference of logarithms, without using exponents. Simplify if possible.
- $$\log _ { 17 } \frac { 5 \sqrt { x } } { y }$$

A) $\log _ { 17 } ( 5 \sqrt { x } ) - \log _ { 17 } y$
B) $\log _ { 17 } y - \log _ { 17 } 5 - \frac { 1 } { 2 } \log _ { 17 } x$
C) $\log _ { 17 } 5 \cdot \frac { 1 } { 2 } \log _ { 17 } \mathrm {~m} \div \log _ { 17 } \mathrm { y }$
D) $\log _ { 17 } 5 + \frac { 1 } { 2 } \log _ { 17 } \mathrm { x } - \log _ { 17 } \mathrm { y }$
