3 ln x − 5 ln(1/y) − 4 ln(xy)
ln%28x%5E3%29+-+ln%28%281%2Fy%29%5E5%29%29 +-+ln%28%28xy%29%5E4%29%29
working on the two left expressions
ln%28%28x%5E3%29%2F%281%2Fy%29%5E5+%29+ +-+ln%28%28xy%29%5E4%29%29
ln%28%28x%5E3%2Ay%5E5%29+%29+ +-+ln%28%28xy%29%5E4%29%29
ln%28%28x%5E3%2Ay%5E5%29+%29+ +-+ln%28x%5E4%2Ay%5E4%29%29
ln%28%28x%5E3%2Ay%5E5%29%2F%28x%5E4%2Ay%5E4%29+%29+
ln%28y%2Fx+%29+ assuming y and x are positive
