exponents, HP50g - tigger - 09-05-2015 03:12 PM
Sometimes I get weird results which look like
e^(h²*e^(n*ln H))
which is equal to
e^(H²*H^N)
Could the HP50g simplify this first result itself? What would be the key-sequence to make the HP50g simplify the result?
Sorry I can not make a photo of the display. Hope it is understandable.

The command you want is EXP2POW (exponential to power). The key sequence is left-shift 6 (CONVERT), F4 (REWRITE), F3 (EXP2POW).
I personally find the tiny program << TSIMP EXP2POW >> to be so helpful for simplifying messy algebraic expressions with exponentials in them, that I keep it assigned to a key.

great,
thanks,
it works

How can I find the program << TSIMP EXP2POW >>?

TSIMP is found on the calculator. EXP2POW is also on the calculator. The statement
Code:
<< TSIMP EXP2POW >>Look up how to write a program in UserRPL, in Chapter 21 in the UserGuide. Some of the chapter may refer to earlier material in the book.
