Answer 1

To convert meters to kilometers, you divide the number of meters by 1,000 (or multiply by \(10^{-3}\)).

So, for \(3.875 \times 10^9\) meters:

\[ \frac{3.875 \times 10^9 \text{ meters}}{1000} = 3.875 \times 10^9 \times 10^{-3} = 3.875 \times 10^{6} \text{ kilometers} \]

Thus, \(3.875 \times 10^9\) meters is equal to \(3.875 \times 10^{6}\) kilometers.

The final answer is:

3.875 × 10⁶ km
