2. Exponents Homework page 1
Write each expression in exponential form
8x8x x7
4x4x4x x5x5x5x5
Find each value 54
At Russell’s school one person will contact 4 people and each of those people will contact 4 others, and so on. How many people will be contacted in the 5th round?

3. Exponents page 2 What is an exponent? What is exponential form?
An exponent tells how many times a number is multiplied by itself.
base->73<- exponent
73=7x7x7=343
A number is written in exponential form when the number or base is written with an exponent.

4. Exponents page 2 continued

6. Exponents page 4 How do you use a tree diagram with exponents?
A tree diagram is used when dealing with word problems and exponents
Ex: A secretary calls 3 families. Then each family calls 3 other families, and so on. How many families will be notified during the 6th round
1st round is the exponent 1, 3 families are called the base 3 which give us 31
Every family calls 3 so the base the round we want is 6 so the exponential number is
36=729
