−4.5866×10^−5

Answer 1

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

1. Rewrite \( 4.66 \times 10^{-5} \) as: \[ 4.66 \times 10^{-5} = 4.66 \times 10^{-5} \times \frac{100}{100} = 4.66 \times 10^{-5} \text{ (keeping it as is)} \]

2. Rewrite \( 7.34 \times 10^{-7} \) with the same exponent as \( 4.66 \times 10^{-5} \): \[ 7.34 \times 10^{-7} = 0.0734 \times 10^{-5} \]

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

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