Answer 1

To divide \(3.3 \times 10^4\) by \(5.5 \times 10^7\), follow these steps:

1. Divide the coefficients:
\[
\frac{3.3}{5.5} = 0.6
\]

2. Subtract the exponents:
\[
10^{4 - 7} = 10^{-3}
\]

3. Combine the results:
\[
0.6 \times 10^{-3}
\]

To express \(0.6\) in scientific notation, it can be rewritten as \(6 \times 10^{-1}\). Therefore, we can substitute this into our previous result:

\[
6 \times 10^{-1} \times 10^{-3} = 6 \times 10^{-4}
\]

Thus, the final answer is:
\[
6 \times 10^{-4}
\]

So the correct response is:

**6×10−4** (6 times \(10\) to the negative 4 power)
