Subtract 4.66×10^−5 −7.34×10^−7 (answers)−4.5866×10^−5 −2.68×10^2 4.5866×10^−5 4.5866 2.68×10^2
The correct answer is 4.5866×10^(-5)
To subtract numbers in scientific notation, follow these steps:
Step 1: Ensure that the exponents are the same. If the exponents differ, adjust one or both of the numbers so that they have the same exponent.
Step 2: Now you can subtract the coefficients (the numbers before the "x10^"). In this case, subtract 4.66×10^(-5) from -7.34×10^(-7).
4.66×10^(-5) - 7.34×10^(-7)
Step 3: Subtract the coefficients:
4.66 - 7.34 = -2.68
Step 4: Keep the exponent the same.
Since both numbers are in scientific notation with the same exponent of -5, the final result will be in scientific notation with the same exponent.
Therefore, the answer is: -2.68×10^(-5)
So, the correct answer is -2.68×10^(-5).
To subtract 4.66×10^−5 from -7.34×10^−7, follow these steps:
1. Make sure both numbers have the same exponent. In this case, write -7.34×10^−7 as -0.734×10^−6.
2. Subtract the decimal parts of the numbers. 0.734 - 0.0466 = 0.6874.
3. Keep the exponent the same. The exponent remains as 10^-6.
4. Write the result in scientific notation. The final answer is -0.6874×10^-6, which can be simplified to -6.874×10^-7.

Apologies for the confusion in the previous responses.
To subtract 4.66×10^(-5) from -7.34×10^(-7), follow these steps:
1. Make sure both numbers have the same exponent. In this case, write -7.34×10^(-7) as -0.00734×10^(-5).
2. Subtract the decimal parts of the numbers: 0.00734 - 4.66 = 0.00268.
3. Keep the exponent the same. The exponent remains as 10^(-5).
4. Write the result in scientific notation. The final answer is 2.68×10^(-3) or 0.00268×10^(-3). The exponent can also be written as 10^(-5), depending on the required format.
Therefore, the correct answer is: 2.68×10^(-3) or 0.00268×10^(-3).
