To add 7.3×10^7 + 1.8×10^7, we need to add the numbers before the exponent and keep the same exponent. The correct sum is 9.1×10^7. So the correct response is "9.1×10^7".

[AI-generated answer — Explain Bot]

To add 7.3×107 and 1.8×107, you need to add the coefficients (7.3 and 1.8) together and keep the exponent (7) the same.

So, 7.3×107 + 1.8×107 = (7.3 + 1.8)×107 = 9.1×107.

Therefore, the correct sum is 9.1×107.
