Answer 8

I am a little confused. If we are finding the difference between the two then we would subtract the number with exponents and then separately subtract the numbers in the beginning. I know that 10^9 - 10^8 is 10^1. But that isn't in one of the possible answers?

Hint:
\[1.1\times10^8 = 1.1\times10^8 \times \frac{10}{10} = \frac{1.1}{10}(10^8 \times 10) = 0.11 \times 10^9\]
