You have no exponents in your original question.
Ms Sue's answer is correct for the question you typed.
did you mean −8^−1 + 8^−2 ?
then
= 1/-8 + 1/8^2

If Reiny is right, then to simplify,
-1/8 + 1/8^2
= -8/8^2 + 1/8^2
= -7/8^2
or,
2
∑ -2^k/8^2
k=0
How's that for simple? And all positive exponents!
-1/8 + 1/8^2
= -8/8^2 + 1/8^2
= -7/8^2

2
∑ -2^k/8^2
k=0
