Multiple Choice

Use properties of logarithms to evaluate the expression.
-Let $\mathrm { u } = \ln \mathrm { a }$ and $\mathrm { v } = \ln \mathrm { b }$ . Write the following expression in terms of $\mathrm { u }$ and $\mathrm { v }$ without using the funct $\ln \left( \sqrt [ 5 ] { a b ^ { 4 } } \right)$

A) $\frac { \mathrm { u } } { 5 } + \frac { 4 } { 5 } \mathrm { v }$
B) $\frac { \mathrm { u } } { 5 } - \frac { 4 } { 5 } \mathrm { v }$
C) $\frac { 4 } { 5 } \mathrm { u } + \frac { 4 } { 5 } \mathrm { v }$
D) $\frac { \mathrm { u } } { 5 } - 4 \mathrm { v }$ n ln.287)
