    Undergrad Another negative one equals one proof

    Hey guys! I need help proving why this proof is wrong. I know it's wrong, but I can't figure out why. Anyway: i = sqrt -1 i^4 = 1 1^4 = 1 Substution: i^4 =1^4 i = 1 1 = sqrt -1 1^2 = -1 1 = 1^2 1= -1 If you have any questions, feel free to ask.
