e^(ln(x)*y) -> x^y
in [HP48]

From: geekerbox on 21 Jan 2008 11:04 Hi, Whenever I get an answer containing e^(ln(x)*y), it doesn't become x^y, even after pressing EVAL again. I'd like to know if there's any flag, setting or command to get the result in the x^y form. Thanks. PS: I own a 50g.

Yes, the 50g likes putting all exponential forms into something containing e by default. To change it back, go to [LS][CONVERT] (the 6 key), choose F4 [REWRITE], and finally F3 [EXP2POW]. Note that if you press EVAL again, it will return to the e^(Y*LN(X)) form. S.C.
