What is i to the power of 3?

The notation "i to the power of 3" represents the complex number i raised to the third power. In mathematics, i is the imaginary unit, which is defined as the square root of -1. When i is raised to the power of 3, it means that i is multiplied by i and then multiplied by i again.

(i)(i)(i) = i^3

Since multiplying by i twice gives -1, i^3 can be simplified as:

i^3 = -i

Therefore, i to the power of 3 is equal to -i.
