Answer: a star that is 5.7 x 10^16 meters away is equal to 5.7 x 10^13 kilometers.
Explanation:
To convert a distance from meters to kilometers, you need to divide the distance in meters by 1,000 because there are 1,000 meters in 1 kilometer.
So, for a star that is 5.7 x 10^16 meters away:
Distance in kilometers = (5.7 x 10^16 meters) / 1,000 meters/kilometer
Now, perform the calculation:
Distance in kilometers = 5.7 x 10^16 / 1,000 = 5.7 x 10^13 kilometers
So, a star that is 5.7 x 10^16 meters away is equal to 5.7 x 10^13 kilometers.
