Final answer:
To add numbers in scientific notation, rewrite the numbers with the same exponent and then add the numbers together. The correct answer is 8.9062 x 10^9.
Step-by-step explanation:
To add the numbers in scientific notation, we need to have the same exponent. In this case, we can rewrite the numbers in the form of (8.9 X 109) + (0.0062 X 109). Now, we add the numbers together, which gives us 8.9062 X 109. Therefore, the correct answer is option B.
