What does i raised to the power of 2 (i²) combine to when multiplied?

When considering the value of i raised to the power of 2, it's helpful to recall that i is defined as the imaginary unit, which is equal to the square root of -1. Therefore, when you calculate i², you are essentially evaluating the expression for the square of the imaginary unit.

The operation can be represented as follows:

i² = (√-1)² = -1.

This result indicates that multiplying the imaginary unit by itself yields -1. This characteristic makes i² fundamental in complex number arithmetic, where the imaginary unit plays a crucial role.

Thus, the answer -1 accurately represents the outcome of the multiplication involving i raised to the power of 2.
