# Math Help - Find Argument, probably easy

1. ## Find Argument, probably easy

if you got z=(-1-sqrt(3)*i)^101
Find arg(z) the answer should be between 0 and 2pi
I just dont get it right no matter how i do...
PLZ help

Write $-1-\sqrt(3)\cdot i$ in polar form,
then you will see that $arg(z)$ is 101
times $arg(-1-\sqrt(3)\cdot i)$ reduced
modulo $2 \cdot \pi$.
