Answer 1

To divide the expression \( \frac{4 \times 10^{7}}{2 \times 10^{-3}} \), we can follow these steps:

1. **Divide the coefficients:** \( \frac{4}{2} = 2 \)
2. **Subtract the exponents for the powers of ten:**
\[
10^{7} \div 10^{-3} = 10^{7 - (-3)} = 10^{7 + 3} = 10^{10}
\]

Combining both parts, we get:
\[
2 \times 10^{10}
\]

Now, it is already in scientific notation.

So, the final answer is:
\[
\boxed{2 \times 10^{10}}
\]
