Find the value of following expression:i + i2 + i3 + i4

i + i2 + i3 + i4 = i + i2 + i2×i + i4= i – 1 + (– 1)×i + 1since i4 = 1, i2 = – 1= i – 1 – i + 1 = 0

Find the value of following expression:
i + i² + i³ + i⁴

i + i² + i³ + i⁴ = i + i² + i²×i + i⁴

= i – 1 + (– 1)×i + 1

since i⁴ = 1, i² = – 1

= i – 1 – i + 1 = 0
