(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

z= 1+i√3

find z^9

2. Relevant equations

3. The attempt at a solution

Arg(z) = pi/3 and |z|=2

so z= 2e^i*pi/3

so z^9 = 2^9 (cos6pi +isin 6pi)

= 512(1) =512

but the answer has negative 512?
