For any number n>1, is |(1/2 + 2/3i)^n|

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?

Simplify (1/2)4th power a. (1/16) b.(1/8) c.(1/4)

Could somebody me with this radical simplification?
