2.68×102

Answer 1

To subtract \( 4.66 \times 10^{-5} - 7.34 \times 10^{-7} \), we need to express both numbers in terms of the same power of 10.

Let's convert \( 7.34 \times 10^{-7} \) to a form with \( 10^{-5} \):

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

Now the subtraction becomes:

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

Calculating \( 4.66 - 0.0734 \):

\[
4.66 - 0.0734 = 4.5866
\]

Thus, we have:

\[
4.66 \times 10^{-5} - 7.34 \times 10^{-7} = 4.5866 \times 10^{-5}
\]

The correct answer is:

**4.5866×10^(-5)** (or \( 4.5866 \times 10^{-5} \)).
