which measurement would be least likely to be written in scientific notation: number of stars in a galaxy , number of grains of sand on a beach, speed of a car , or population of a country? Explain
Scientific notation is used when a number is really big (example: 11200000000) or really small (example: .000000000002). In this case three of your situations would have really big numbers. That means the answer would be the speed of a car because that would a normal sized number.
