B. −2.68×10^2

C. 2.68×10^2

D. 4.5866×10^−5

Answer 1

To subtract these numbers, we need to ensure that they have the same exponent.

Converting 7.34×10^−7 to scientific notation with the same exponent as 4.66×10^−5, we get 0.0734×10^−5.

Now we can subtract the numbers:

4.66×10^−5 - 0.0734×10^−5 = (4.66 - 0.0734) × 10^−5 = 4.5866 × 10^−5

Thus, the correct answer is D. 4.5866×10^−5.
