x.x.x.x.x/2y you mean expanded form?

You can use the rule of logarithms -- specifically, that division turns into subtraction: \[\ln{\frac{x^5}{2y}} = \ln x^5 - \ln 2y\]

I believe, but it depends on what `expand' means :) That's fairly typical, though.

one more step. \[5ln(x)-ln(2y)\] \[2ln(x)-ln(y)-ln(2)\]

typo in the last one. should be \[ln(\frac{x^5}{2y})=5ln(x)-ln(y)-ln(2)\]
