Question 26756
to solve this you need to know the 4 basic powers of i.
   i^1=square root of -1=i
   i^2=-1
   i^3=-i
   i^4=1
to find i to any power you just take that number and divide it by 4.
in this case 235/4=58.75
Forget about the whole number, just look at the decimal if the decimal was
.25=i
.50=-1
.75=-i
no remainder equals 1
