Question: 4. Solve for the complex value z = a + bi or z = |z|cis(theta) (that is, you may give your answer in either form):

4. Solve for the complex value z = a + bi or z = |z|cis(theta) (that is, you may give your answer in either form): ( Keep Demoivre's theorem in mind)

(a) iz = |4 - 3i| - (2 - i)(3 + i)

(b) iz - (2 + i)² = 2 + i

(d) z³ = - 8

(e) z³ = - 1 + i
