1. Exponents Mr. Platt

2. What is an exponent? An An exponent tells how many times a number called the base is used as a factor. 3 4 Base Exponent

3. Another way of saying it: An An exponent tells how many times a number is multiplied by itself. 3 4 Base Exponent

4. What an Exponent Represents An exponent tells how many times a number is multiplied by itself. An exponent tells how many times a number is multiplied by itself. 3 4 = 3 x 3 x 3 x 3

5. How to read an Exponent This This exponent is read three to the fourth power. 3 4 Base Exponent

6. How to read an Exponent This This exponent is read three to the 2 nd 2 nd power or or three squared. 3 2 Base Exponent

7. How to read an Exponent This This exponent is read three to the 3rd power or or three cubed. 3 3 Base Exponent
