When you say, "Solve," do you mean evaluate? You should try converting it to trigonometric form, or, even better, to the form $r\cdot e^{i \theta}$ .

To add to JBL's clue -- do you know what De Moivre's theorem says? One you know how to write complex numbers in the form JBL suggested, De Moivre's theorem is an extremely powerful tool for working with complex numbers.
