Answer:

To subtract the given numbers in scientific notation, we need to ensure that the exponents are the same. 4.66 x 10^-5 can be written as 0.0000466 in standard form, and 7.34 x 10^-7 can be written as 0.000000734 in standard form. Now, let's subtract these two numbers: 0.0000466 - 0.000000734 = 0.000045866 To express this answer in scientific notation, we need to move the decimal point to the right until there is only one digit to the left of the decimal point. 0.000045866 = 4.5866 x 10^-5 So, the correct answer is option A: 4.5866 x 10^-5.
