Ch. 1 Exponents Exponent: tells how many times a # is multiplied by itself. Ex. 24 = 2 x 2 x 2 x 2 63 = 6 x 6 x 6 Exponential Form: when a # is written with a base and an exponent. Ex. 103 is in exponential form…10 is the base, 3 is the exponent How you say exponents: **Most of the time you will here “10 to the 3rd power” or “2 to the fourth power” or “6 to the third power”. **Here are some other ways to say “to the 2nd power and 3rd power”: 82 is “8 squared” 53 is “5 cubed” **Any number to the 0 power = 1** Ex. A phone tree is used to contact families at Paul’s school. The secretary calls 3 families. Then each family calls 3 other families, and so on. How many families will be notified during the fourth round of calls? (Most of you would draw a tree diagram. However, you can easily do 3 to the 3rd power)
