question 144

Multiple Choice

Use properties of logarithms to expand the logarithmic expression as much as possible. Where possible, evaluate
logarithmic expressions without using a calculator.
- $\log _ { b } \left( \frac { x y ^ { 7 } } { z ^ { 2 } } \right)$

• A) \(\log _ { \mathrm { b } } \mathrm { x } + 7 \log _ { \mathrm { b } } \mathrm { y } - 2 \log _ { \mathrm { b } } \mathrm { z }\)
• B) \(\log _ { \mathrm { b } } \mathrm { x } + \log _ { \mathrm { b } } \mathrm { y } ^ { 7 } - \log _ { \mathrm { b } } \mathrm { z } ^ { 2 }\)
• C) \(\log _ { \mathrm { b } } \mathrm { x } + \log _ { \mathrm { b } } \mathrm { y } ^ { 7 } + \log _ { \mathrm { b } ^ { \mathrm { z } } } 2\)
• D) \(\log _ { \mathrm { b } } \mathrm { x } + 7 \log _ { \mathrm { b } } \mathrm { y } + 2 \log _ { \mathrm { b } } \mathrm { z }\)
