Zayne Moreno · Answer 1

-i

Step-by-step explanation:

Our number is i = √-1, and we want to find i³, which is essentially just i * i * i, so:

i³ = i * i * i = √-1 * √-1 * √-1 = - 1 * √-1 = - 1 * i = - i

The answer is - i.

Lilyana Huynh · Answer 2

-i

Step-by-step explanation:

i = sqrt (-1)

i² = - 1

i³ = i² * i = - 1 * i = - i
