# What is the scientific notation for 500?

The scientific notation for 500 is $5$ x ${10}^{2}$. To change 500 to scientific notation, move the decimal (understood to be at the end of the number) two spaces to the left so that only the 5 is to the left of the decimal. This makes the exponent a positive 2, indicating that when the number is expanded, the decimal will be moved to the right 2 places.
