    Simply add/subtract the real and imaginary parts separately and express in "a+ib" form!

    okay do you know that i^2 =-1, i^3=-i, i^4=1, i^5=i again, i^6=-i... and so on? what would i^7 be according to this trend?

    here's a hint for you!! if the exponent is odd (except for 3) the answer is -i if the exponent is even (other than 2) the answer is 1
