Answer by Alan3354(30993)   (Show Source): You can put this solution on YOUR website!Hi. I need help finding the three cube root of -2-2i. ----------------- Are you familiar with the Argand diagram? The magnitude is 2sqrt(2), and the angle is 225degs. Add 360 and 720 degrees, and divide by 3 for the angles of the 3 cube roots. -------------------- You get 75, 195 and 315 degrees. The magnitude of the cube root is the original magnitude * 1/3. Is that sufficient? email me via the thank you note if you have further questions, or to check your work.
