ln M/N =ln M-N
ln M^x = xlnM
apply these rules
3lnx -1/3 lny = ln x^3/y^1/3
Condense the logorithmic expression as much as possible:
3 ln x -(1/3) ln y
The answer is ln x^3 / 3(radical)y
Can a process be provided as to how one gets to the answer? I think I see what is happening, but could use clarification.
