Use Properties of Logarithms to Condense the Logarithmic Expression $$\log _ { \mathrm { c } } \mathrm { x } + \log _ { \mathrm { c } } \mathrm { y }$$

question 8

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.
- $$\log _ { \mathrm { c } } \mathrm { x } + \log _ { \mathrm { c } } \mathrm { y }$$

• A) \(\log _ { C } \mathrm { x } \cdot \log _ { \mathrm { c } } \mathrm { y }\)
• B) \(\log _ { \mathrm { C } } \left( \frac { \mathrm { x } } { \mathrm { V } } \right)\)
• C) \(\log _ { \mathrm { C } } ( \mathrm { xy } )\)
• D) \(\log _ { \mathrm { C } } ( \mathrm { x } + \mathrm { y } )\)
