-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 functi $\ln \left( b ^ { 9 } \sqrt [ 4 ] { a } \right)$

A) $9 v + 4 u$
B) $9 v + \frac { u } { 9 }$
C) $9 v - \frac { u } { 4 }$
D) $9 v + \frac { u } { 4 }$
