Question

Convert 3.875*10^9 meters to kilometers. Express the answer to the exact decimal place. 1 kilometer is equal to 1000 meters.

Answer 1

To convert from meters to kilometers, we need to divide the number of meters by 1000, since there are 1000 meters in 1 kilometer.

3.875 * 10^9 meters = (3.875 * 10^9) / 1000 kilometers

Now we can simplify this expression:

(3.875 * 10^9) / 1000 = 3.875 * 10^9 / 10^3

According to the rules of division with exponents, when dividing numbers with the same base, we subtract the exponents:

3.875 * 10^9 / 10^3 = 3.875 * 10^(9-3)

3.875 * 10^(9-3) = 3.875 * 10^6 kilometers

Therefore, 3.875 * 10^9 meters is equal to 3.875 * 10^6 kilometers.
