i squared square root 80

MathMate,
It would be clearer if you had written √ using the sqrt() notation, since the range of the square root would be clear.
I have to guess that the question is:
i squared square root 80
=i² * *radic;(80)
(=i^2 * sqrt(80))
=(1) * sqrt(2^4 * 5)
=(1) * 2²sqrt(5)
=4sqrt(5)i
