1 answer

To subtract the given numbers in scientific notation, we need to subtract their coefficients and keep the same exponent.

The coefficient for the first number is 4.66, and the coefficient for the second number is 7.34. Subtracting these gives us: 4.66 - 7.34 = -2.68

Therefore, the coefficient for the result is -2.68.

Since both numbers have a negative exponent, the result will also have a negative exponent.

Thus, the final answer is -2.68 x 10^-5.

Therefore, the correct answer is A. -4.5866 x 10^-5.
