Question 21. Let i denote the square root of –1. Suppose w=2– 3i. Find three cube roots of w in the exponential form. Note the arguments should be given as principal arguments [–x, T) in radians up to 3 decimal places. a) wo = V13e0.328i, w1 = V13e2.422i b) wo = V13e-0.328i c) wo = V13e-0.983i d) wo = 13e-0.328i e) not in the list W2 = V13e4.516i W2 = V13e1.767i W2 = V13e1.583i w2 = V13e-1.767i Wi = V13e2.422i Wi = V13e5.300i = V13e?422i Wi =·
