%28sqrt%28-3%29+%2Bi%29%5E6 ? %28sqrt%283%29%2Bi%29%5E6 ?

%28sqrt%283%29%2Bi%29%5E6 has more charm as a problem,
because sqrt%283%29%2Bi has a real part, sqrt%283%29 and an imaginary part 1%2Ai ,
so it begs for using the polar form.
r=sqrt%28%28sqrt%283%29%29%5E2%2B1%5E2%29=sqrt%283%2B1%29=sqrt%284%29=2
tan%28theta%29=1%2Fsqrt%283%29=sqrt%283%29%2F3 , so system+%28theta=pi%2F6%2C%22or%22%2Ctheta=pi%2Bpi%2F6%29 ,
but since sqrt%283%29%3E0 and 1%3E0 , it must be theta+=pi%2F6 , in the first quadrant.
So, sqrt%283%29%2Bi=2%28cos%28pi%2F6%29%2Bi%2Asin%28pi%2F6%29%29 and
%28sqrt%283%29%2Bi%29%5E6=2%5E6%28cos%28pi%29%2Bi%2Asin%28pi%29%29=64%28-1%2Bi%2A0%29=-64 .

is a real number,
but from then on it gets complicated.
