To subtract 4.66×10^(-5) from 7.34×10^(-7), you need to subtract the coefficients and keep the same exponent.
Coefficient subtraction: 4.66 - 7.34 = -2.68
Exponent remains the same: 10^(-5)
Therefore, the result is -2.68×10^(-5).
To subtract the numbers in scientific notation, we need to ensure that the exponents are the same. In this case, the exponents are both negative, so they can be directly subtracted.
1. Start by subtracting the coefficients (the numbers before the "x10"):
4.66 - 7.34 = -2.68
2. Keep the same exponent, which is -5 in this case.
3. Write the answer in scientific notation format:
-2.68 x 10^(-5)
So, the correct response is "-2.68 x 10^(-5)".
