I have to find (i)^1/3 and have no idea where to begin.

This is a multiple choice question. My choices are a. Sq. root of 3/2 - 1/2i; b. -sq.rootof 3/2 + 1/2i; c. sq.rootof 3/2 + 1/2i; d.1/2 + sq.rootof 3/2i

I have tried this a few different ways and canot get any of these answers. What am I doing wrong? Thank you for your help.
