#### What are the Powers of i?
There is a wide variety of numbers in math. We come across real numbers, whole numbers, integers, complex numbers, and imaginary numbers. Out of these, imaginary numbers are those that are written with ‘iota,' represented by ‘i.'
When learning about imaginary numbers, we come across the property of iota that is; i^{2}= -1, i= √(-1). While every student is aware of this but not many know how to tackle the higher power of iota. But we are here to help you.
We can use the property of iota to work out the higher powers. For instance, you must work out the value of i^{3}. What you need to do here is break this using the property of iota. You can write this as; i^{3} = i^{2}. i=-1.i=i.
You see how we used the property of iota to work out the higher powers. Let us take another example here. What is the value of i^{4}.
We can split this into i^{2}. i^{2} = (-1).(-1) = 1.
This is how you work out the powers of iota.
