copyright©amberpasillas2010 An exponent is a little number high and to the right of a regular or base number. 8 3 Base Exponent

copyright©amberpasillas Base Exponent This exponent is read 8 to the 3rd power, or 8 cubed.

copyright©amberpasillas Base Exponent An exponent tells how many times a number is multiplied by itself.

copyright©amberpasillas Base Exponent This exponent means 888 = 512

copyright©amberpasillas2010 This exponent is read six to the fourth power. 6 4 Base Exponent

copyright©amberpasillas2010 This exponent is read three to the 2 nd 2 nd power or three squared. 3 2 Base Exponent

copyright©amberpasillas2010 Read These Exponents 7 7 to the 2 nd power or 7 squared 2

Read These Exponents to the 3 rd power or 10 cubed 3

copyright©amberpasillas2010 What is the Exponent? (bc)(bc)(bc) = (bc) 3 NOTICE that you keep the parenthesis around the variables (bc) because you are cubing all the (bc)
