Guest jmcgigge Posted April 28, 2004 Share Posted April 28, 2004 I'm trying to find a proof for the following equation: x*y^ln(x)=x^ln(y)+1 It works when I punch it into my TI-89, but I can't figure out why... Link to comment Share on other sites More sharing options...

MandrakeRoot Posted April 29, 2004 Share Posted April 29, 2004 How about x^(ln y + 1) = exp( (lny + 1)lnx ) = exp (ln x) exp(ln x ln y) = x y^(ln x) Remember that by definition x^alpha is defined as exp (alpha ln x) Mandrake Link to comment Share on other sites More sharing options...
