Question 869904
3 ln x − 5 ln(1/y) − 4 ln(xy)
{{{ln(x^3) - ln((1/y)^5))}}} {{{ - ln((xy)^4))}}}
working on the two left expressions
{{{ln((x^3)/(1/y)^5 ) }}} {{{ - ln((xy)^4))}}}
{{{ln((x^3*y^5) ) }}} {{{ - ln((xy)^4))}}}
{{{ln((x^3*y^5) ) }}} {{{ - ln(x^4*y^4))}}}
{{{ln((x^3*y^5)/(x^4*y^4) ) }}}
{{{ln(y/x ) }}} assuming y and x are positive
