Scientists use scientific notation as a way of writing numbers primarily because they often deal with very small or very large numbers. In this case, the Earth's circumference at the equator which is equal to 40,075,017 m can be expressed in terms of scientific notation by multiplying it to a factor of 10. The scientific notation is 4.0075 x 10^7 m.
