Use the Properties of Logarithms to Rewrite the Expression logbx2y4z73\log _ { b } \sqrt [ 3 ] { \frac { x ^ { 2 } } { y ^ { 4 } z ^ { 7 } } }

Question 187

Multiple Choice

Use the properties of logarithms to rewrite the expression. Simplify the result if possible. Assume all variables represent
positive real numbers.
- logbx2y4z73\log _ { b } \sqrt [ 3 ] { \frac { x ^ { 2 } } { y ^ { 4 } z ^ { 7 } } }


A) 2logbx4logby7logbz2 \log _ { b } x - 4 \log _ { b } y - 7 \log _ { b } z
B) 23logbx43logby73logbz\frac { 2 } { 3 } \log _ { b } x - \frac { 4 } { 3 } \log _ { b } y - \frac { 7 } { 3 } \log _ { b } z
C) 13logbx2logby4logbz7\frac { 1 } { 3 } \log _ { b } x ^ { 2 } - \log _ { b } y ^ { 4 } - \log _ { b } z ^ { 7 }
D) 23logbx÷(43logby73logbz) \frac { 2 } { 3 } \log _ { b } x \div \left( \frac { 4 } { 3 } \log _ { b } y \cdot \frac { 7 } { 3 } \log _ { b } z \right)
