First rule means: if you have 4 ln 6, you can also write it as:\[\ln 6^4\] Also: 2 ln 2 is the same as:\[\ln 2^2 = \ln 4\] So your problem now is a little smaller:\[\ln 6^4  \ln 4\] The seond rule says: \[\ln 6^4  \ln 4 = \ln \frac{ 6^4 }{ 4 }\]If you work out what \[\frac{ 6^4 }{ 4 }\]is, you have the answer.
