Exponents Homework page 1 • Write each expression in exponential form • 8x8x8 2. 7x7 • 4x4x4x4 4. 5x5x5x5x5 Find each value 5. 42 6. 33 • 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?
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 exponentialform when the number or base is written with an exponent.
Exponents page 2 continued • What is the exponential form of 4x4x4? • What is the exponential form of 9x9x9x9x9? • What is the value of the exponential form 37? • Answer:43 • Answer:95 • Answer: 3x3x3x3x3x3x3=2,187
Exponents Page 3 • Do now • Put these into exponential form and solve • 4x4x4 • 3x3x3x3 • 5x5x5x5
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
