You should have : x^2 / (cube root of x^3-8)^2, close to but not the fractional power you want. I'm a new user and after going thru the AUR twice, nothing comes back to me in this regard. Any suggestions? ☺ Re: Reduce fraction on HP50G - Glenn Shields - 03-12-2010 Sorry, that was my attempt at "alt + 1" with num-lock on, which is supposed to return a smiley. It appeared, really. Thanks, Glenn
