    -i

    Step-by-step explanation:

    i = sqrt (-1)

    i² = - 1

    i³ = i² * i = - 1 * i = - i

    -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.
