# Distinct solution in complex plane Watch

1. (Original post by meme12)
Yes I did similar one too , is it right
z3-8i=o
will be = 8 e^i(pi/2+2npi)
= 8 e^i pi/2(1+4npi)
z0= 8(cos pi/2+isinpi/2)
What is z0 supposed to be?

You are correct that

so now you need to find the 3 distinct cube roots of that number.
