Answer:
Step-by-step explanation:
The iota is a complex notation represented by the letter i in complex number.
iota power 2 can also be written as;
i^2
In complex number, the square root of -1 is iota. This can be expressed as;
[tex]\sqrt{-1} = i[/tex]
Take the square of both sides
[tex](\sqrt{-1})^2 = i^2\\-1 = i^2\\Rearrange\\i^2 = -1[/tex]
Hence the iota power 2 is equal to -1
