Question

If i = StartRoot negative 1 EndRoot, what is the value of i 3? –1 i 1 –i

Answer 1

Answer:

-i

Step-by-step explanation:

i = sqrt(-1)

i² = -1

i³ = i² × i = -1 × i = -i

Answer 2

Answer:

-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.
