Simplify logarithms to rewrite the following expressions in terms of u and t. Let ln x=t and ln y = u.
[(ln x)^3  ln (x^4)] / (lnx/e^2)ln(xe^2)
This problems is stumping me!!!! I don't know what to do, since some lnx are inside parentheses and others aren't.

Best ResponseYou've already chosen the best response.1well i don't know where is 'y' in the equation, but anyway the solution of this equation : [(ln x)^3  ln(x^4)] /[ln (x/e^2)ln(xe^2)] = [(ln x)^3  4ln(x)] / [ ( ln(x)  ln(e^2)] [ ln(x) + ln(e^2) ] ; and now ln(x) =t; t [ t^2 4 ] / [( t 2ln(e)] [t + 2ln(e)] = t[ (t  2) (t +2 )] / [ ( t  2 ) ( t + 2 ) ] = t = ln(x)

Best ResponseYou've already chosen the best response.0Thank you!!! This is great :) Yes, I didn't mean to add the Y there. Just meant to have t.
