Exponents tell us how many times a number (called a base) is multiplied by itself. A base with an exponent is “raised to a power (the exponent).” We can show repeated multiplication in a shorter form by using exponents. Any base raised to the first power equals itself. Any base raised to the zero power is one. Any base raised to a negative exponent has a value less than one, and your answer will be a fraction or decimal. When in doubt about how to apply an exponent, write the expression out in expanded form and simplify.
