Question

Let z=−93√−9i.

When z is graphed in the complex plane, what radian angle does it make with the positive x-axis?

What radian angles do z2, z3, and z4 make with the positive x-axis?
z2:
z3:
z4:

For what values of n does z^n lie on the positive x-axis?


For the purposes of this problem, report all angles as their smallest positive equivalent.
