Question

Answer this question​

Answer 1

i^2=-1

i^4=1

now,make convert powers to 4 multiples..

i^592=[(i^4)^148]=1

i^590=[(i^4)^147]×i^2=-1

i^588=[(i^4)^147]=1

i^586=[(i^4)^146]×i^2=-1

i^584=[(i^4)^146]=1

i^582=[(i^4)^145]×i^2=-1

i^580=[(i^4)^145]=1

i^578=[(i^4)^144]×i^2=-1

i^576=[(i^4)^144]=1

i^574=[(i^4)^143]×i^2=-1

substituting above value we get answer -1
