Question 5 20 pts Any nonzero complex number has n nth roots. The principal nth root of r(cos 0 + isin 0) is vr ( cos - + isin and the n n other roots are evenly spaced in a circle around the origin; they 360 have the same radius but the angles differ by n Question: What are the fourth roots of 625(cos 120" + i sin 120" )?
