Answer 1

To perform the subtraction \( 4.66 \times 10^{-5} - 7.34 \times 10^{-7} \), we first need to express both numbers with the same exponent.

The term \( 7.34 \times 10^{-7} \) can be rewritten in terms of \( 10^{-5} \):

\[ 7.34 \times 10^{-7} = 0.0734 \times 10^{-5} \]

Now, substituting this into the original expression gives:

\[ 4.66 \times 10^{-5} - 0.0734 \times 10^{-5} \]

Next, we can perform the subtraction:

\[ (4.66 - 0.0734) \times 10^{-5} = 4.5866 \times 10^{-5} \]

Thus, the result of the subtraction is:

\[ 4.5866 \times 10^{-5} \]

So the correct response is:

4.5866×10−5
