Write it in both Cartesian and polar forms. Roots ex. Find the fifth roots of 32. 1. Write the number in polar form. 2. Find one fifth root. 3. The other roots are spaced evenly around a circle at intervals of 2 ! # of roots = 2 5 ex. Find the fourth roots of z = ! 81 2 ! 81 3 2 i . Do: 1. Let z = 3 + i , w = 2 i Find z 1 w ! " # $ 2.
