RE: Roots of Complex Numbers (Sharp, TI, Casio)
step by step solutions by using DeMoivre's theorem

So similarly for TI-30X Pro:
1. step: enter complex number 15625+0.719413999i
2. get magnitude and angle, optionally you can store these values to memory, e.g. magnitude to x and angle to y
3. enter n-th root from magnitude, enter angle symbol (menu "complex" - option 1), enter angle divided by the n
4 press enter to get result
for n=4:
x^(1/4)<y/4
11.18033989+0.000128693i

n-th root with 2 steps only
