The 15C manual has a problem that is intuitive on that platform and on the 35S, but not for me on the 34S: 2i(-8+6i)^3/(4-2sqrt5i)*(2-4sqrt5i) The answer is ~ 9.3982-35.1344i Thanks for any help! Re: HP 34S complex # problem - Gerson W. Barbosa - 02-17-2013 Assuming you mean ```2i(-8+6i)^3/((4-2sqrt(5)i)*(2-4sqrt(5)i)) ``` and stack size is set to 8, ```SSIZE8 ``` then a possible keystroke sequence is ```2 ENTER 0 ENTER 6 ENTER 8 +/- ENTER 0 ENTER 3 CPX y^x CPX * 5 SQRT 2 +/- * 4 ENTER 5 SQRT 4 +/- * 2 CPX * CPX / ``` This returns ``` --> 9.39820200952 x<>y --> -35.1343865997 ``` HTH Edited: 17 Feb 2013, 6:57 p.m. Re: HP 34S complex # problem - Richard Berler - 02-17-2013 Thanks! I think that I can get comfortable with this.
