Question 5 of 10 • MO-Algebra II A

If z = 2 + 2i, what is z4?

Answer

2 square root 2 (cosine ( StartFraction pi over 4 EndFraction) plus i sine (StartFraction pi over 4 EndFraction))

2 square root 2 (cosine (pi) plus i sine (pi))

64 (cosine ( StartFraction pi over 4 EndFraction) plus i sine (StartFraction pi over 4 EndFraction))

64 (cosine (pi) plus i sine (pi))
