Best ResponseYou've already chosen the best response.3its very easy all you do is you have to remember some formulas i^2 = 1 , i^3 = 1 , and i^4 = 1

Best ResponseYou've already chosen the best response.0yes now if you wrote out i^120 it would be (i*i*i*i) * (i*i*i*i) * .... * (i*i*i*i)

Best ResponseYou've already chosen the best response.0The first step to understanding this is to understand that you have 1*1*1*1*...*1 (30 times) if the problem were i^121 (one more i), it would be 1*1..*1 * i one i left over

Best ResponseYou've already chosen the best response.0once you get the idea, you can use the idea of exponents \[ i^{ab} = (i^a)^{b} \]
