Question 631743
[2-2 sqrt (3i)]^10.  Write your answer in exact rectangular form.
If you mean [2 - 2sqrt(3)i]^10
---------------
r = sqrt(4 + 12) = 4
tan = -sqrt(3) --> angle = 300 degs
--> 4cis(300)
^10 --> 4^10cis(3000)
= 2^20cis120
= 2^20*(-0.5 + i*sqrt(3)/2)
= 2*19*(-1 + isqrt(3))
----------
or 
-524288 + i*524288*sqrt(3)
