If turned off, you will get the real result -1. If turned on, you will get the complex result -0.809016994375+0.587785252292*i. Also, I think the CAS mode always approximates to the complex result. HP Prime emulator, 2.1.14181 (2018_10_16), just after a hard reset. From Symbolic Setup, if I pick Complex: Off, (-1)^(4/5) gives -0.809016994375+0.587785252292*i. If I pick Complex: System, or On, (-1)^(4/5) give "Error: (X<0)^(∉Z)" I was unable to setup calculator to give real root for (-1)^(4/5) = 1.0 |
