BINGO! (Re: logx y) Message #3 Posted by GWB on 12 June 2005, 1:16 p.m., in response to message #2 by Tom Sherman
Hi Tom,
Congratulations! Most likely you have made use of mathematical properties of logarithms to solve the problem. In fact, it can be shown that lny/lnx=ln(y^(1/lnx)). I must confess I found this out entirely by chance, playing with the 32Sii keyboard for a while. On the 33S my unorthodox method would have been even easier, as the [x xroot y] is not a shifted key :-)
Thanks for your having appreciated the problem.
For other HP scientific calcs (except the HP-35): [LN] [1/x] [y^x] [LN]

Cheers,
Gerson.
