The correct response is: 4.5866×10−5
To subtract 4.66x10^-5 - 7.34x10^-7, you need to subtract the coefficients and keep the same exponent.
4.66x10^-5 - 7.34x10^-7 = 4.66 - 0.734 = 3.926 x 10^-5
So, the answer is 3.926 x 10^-5 or 3.926x10^-5.
To subtract the given numbers in scientific notation, you need to ensure that the exponent (the superscript) is the same for both numbers. In this case, both numbers have an exponent of -5.
To subtract the numbers, subtract the coefficients (the numbers in front of the "x10") while keeping the exponent the same.
So, the calculation would look like this:
4.66×10^(-5) - 7.34×10^(-7)
To subtract the coefficients, subtract 7.34 from 4.66:
4.66 - 7.34 = -2.68
Since the exponent remains the same, the final answer is:
-2.68 × 10^(-5)
