Re: Programming challenge (HP 12C) - mapet - 03-28-2002 My solution is 4 steps long, but it seems that you've already guessed it ... :-) BTW y^x makes it 5 steps long. I have to work on more difficult challenge next time... Re: Programming challenge (HP 12C) - Frank Glitz - 03-28-2002 > I have to work on more difficult challenge next time... Not really! Just don't allow the usage of these functions of the 12C. That's a little harder nut to crack (for someone whose math courses are long-forgotten, like me ;-) Someone remembers how to do?

Re: Programming challenge (HP 12C) - Thibaut.be - 03-28-2002 I guess this is you solution : y = e^((ln x)/3) so the steps are : 01 43 23 g e^x 02 3 3 03 10 / 04 43 22 g LN Note how it is easy in a HP to calculate a apperently more complicated formula... Re: Programming challenge (HP 12C) - John Ioannidis - 03-28-2002 Why is this even a challenge? [3] [1/x] [y^x] three steps, three keystrokes.
