i the Imaginary Number

i = imaginary unit

The letter i, when use to represent a number is known as “the imaginary number”.

Given the definition of i both of the following statements are true:
i^2 = -1 and i =  {sqrt{-i}}

i^0 = 1
Any number with an exponent of 0 is equal to 1.

i^1 = i

i^2 = -1

i^3 = -i
Solution:
i^3 = i^2 * i
if:
i^2 = -1
then
i^3 = -1 * i = -i

i^4 = 1
Solution:
i^4 = i * i^3
if
