Answer 1

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

Convert \( 7.34 \times 10^{-7} \) to have the same exponent as \( 4.66 \times 10^{-5} \):

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

Now we can perform the subtraction:

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

Calculating \( 4.66 - 0.0734 \):

\[ 4.66 - 0.0734 = 4.5866 \]

So the result is:

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

Thus, the final answer is:

4.5866×10^−5.
