Evaluate i to the power of 3.

'i', called 'iota', is defined as the square root of negative 1. It is used to represent a complex number. It is an imaginary number.

Answer: The value of i to the power of 3 is equal to i³ = -i.

Let's look into the steps below

Explanation: 

We know that the value of 'i' iota is the square root of negative 1.

It is represented as i = √-1

We know that i² = (√-1)² = -1

Let's evaluate the value of i³

⇒ i³ = i² × i = -1 × i = -i

Thus, we see that the value of i to the power of 3 is equal to  i³ = -i.
