Answer -i Note that the exponentiation of i is cyclic. i to the 0=1 i to the 1 =i i squared = -1 i to the third = -i and i to the fourth is the same as i to the 0=1 since -ixi=1 So i to the 5 is same as i to the 1 or i. So we multiply 15x4 =60 and we can ignore those powers and just look at i to the 3 which we said is -i So i to the 63 =-i
