-2.68 x 102

Answer 1

To subtract the numbers in scientific notation, we first need to express them with the same exponent if necessary.

The numbers we want to subtract are:
- \(4.66 \times 10^{-5}\)
- \(7.34 \times 10^{-7}\)

First, we need to convert \(7.34 \times 10^{-7}\) into the same exponent as \(4.66 \times 10^{-5}\).

To do this, we will express \(7.34 \times 10^{-7}\) with an exponent of \(-5\):
\[
7.34 \times 10^{-7} = 0.0734 \times 10^{-5}
\]

Now we can perform the subtraction:
\[
4.66 \times 10^{-5} - 0.0734 \times 10^{-5} = (4.66 - 0.0734) \times 10^{-5} = 4.5866 \times 10^{-5}
\]

Therefore, the answer is:
\[
\boxed{4.5866 \times 10^{-5}}
\]
