Here's the question you clicked on:

i^36
i^4=1 (i^4)^9=1^9=1
i^1=i 1^2=-1 i^3=-i i^4=1 i^5=i see a pattern?
k.....u know i^2 = -1 .....................i^4 = 1 Check how many 4s are there in 36 or better still divide 36 by 4
so i's are the result off odds and 1's are the result of evens?
no not exactly i when raised to a number which is a factor of 4 will give you one
i raised to even number not a factor of four will give you -1
oooooh okay thanks :)
