HP 34S complex # problem Richard Berler Unregistered Posts: 109 Threads: 38 Joined: Dec 2012 02-17-2013, 06:03 PM I can't get the hang of working complex # problems on the 34S. 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!
