Concept:

Iota is an imaginary unit number symbolized by the letter I and its value is  √-1 i.e., i = √−1.

Given:

$i^{31}$

To find:

The power of $i^{31}$

Solution:

Here we have been given an $i$ function with an odd power. So we know when the power of i is odd and greater than 4 then the value of i is -1. Also, in this question, the power of i is greater than 4 and is an odd number. Hence, the value  $i^{31}$ is -1.
