Calculator gurus !! I need your help to write some complex function!!

Hi guys

I have the complex function z=-3+4 i and I need to get z^5/4 in complex mode. do you know how to do this in a TI calculator? like voyage 200 or Titanium 89?

thanks

Maybe try(for TI 89):

f2 --> A:Complex --> cSolve(z=(-3+4i)^(5/4),z)

That should give an answer, don't know what you're looking for though

But if z = -3+4i and you're looking to find z^(5/4) my calculator is saying its -6.96+2.73i
