You may be able to do this problem like this -
take the exponent and divide the exponent by 4, if the remainder is 0 then the answer is 1, if the remainder is 1 then the answer is i, if the remainder is 2, then the answer is -1, if the remainder is 3, then the answer is -i.
Hope this will help you.
