Answer 1

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

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

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

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

4. To express \(0.6\) in scientific notation:
\[
0.6 = 6 \times 10^{-1}
\]

5. Thus, the expression becomes:
\[
6 \times 10^{-1} \times 10^{-3} = 6 \times 10^{-4}
\]

Therefore, the answer to \( \frac{3.3 \times 10^4}{5.5 \times 10^7} \) is:
\[
6 \times 10^{-4}
\]

The correct response is **6×10−4** (6 times 10 to the negative 4 power).
