Find roots of complex numbers
WebTo find a square root of a given complex number z, you first want to find a complex number w which has half the argument of z (since squaring doubles the argument). Compute r = z and let w = z + r; thus w lies r … WebSo the 4th roots of w are: 81 4 e − i π / 8, 81 4 e 3 i π / 8, 81 4 e 7 i π / 8, 81 4 e 11 i π / 8, Where 81 4 denotes the unique real positive 4th root of 81. By algebraic considerations, we know there are exactly 4 4th roots. So these are all of them.
