# How much is i to the power of 2?

In mathematics, the imaginary unit number is used to express complex numbers and Iota is an imaginary unit number that is denoted by 'i' and the value of iota is √-1.

## Answer: The value of i to the power of 2 is -1.

Let's solve this question by using the exponent rules.

**Explanation:**

We know that the value of iota, i = √−1

If we square both sides, we get:

i^{2} = (√−1)^{2}

i^{2 }= -1
