To subtract \( 4.66 \times 10^{-5} - 7.34 \times 10^{-7} \), we need to express both numbers with the same exponent.
First, we can convert \( 7.34 \times 10^{-7} \) to the same exponent as \( 4.66 \times 10^{-5} \):
\[ 7.34 \times 10^{-7} = 0.0734 \times 10^{-5} \]
Now we can rewrite the subtraction:
\[ 4.66 \times 10^{-5} - 0.0734 \times 10^{-5} \]
Now, we can perform the subtraction:
\[ (4.66 - 0.0734) \times 10^{-5} = 4.5866 \times 10^{-5} \]
Thus, the result of \( 4.66 \times 10^{-5} - 7.34 \times 10^{-7} \) is:
\[ 4.5866 \times 10^{-5} \]
So, the correct response is:
4.5866×10−5
