I am really trying to understand but my test is approaching and i could.t wrap my head around this material |Z|^2 is a Real number so you mean that |z|^4 is Real number also? I am trying from two days to understand those rots of unity. I don't understand whiht is the 9th primitive...

I don't know what is the interesting fact behind Z^4?

I have some math problems What is the solution to this equation : z dash(complex conjugate) = z^3 Z is complex number I try to multiply both sides by Z in the left i get Z dash Z => |Z| but i don't see the solution ---- P is primitive 9th root of unity. Calculate the sum 1 + 2P...
