1. Exponents We are learning to…simplify expressions that contain exponents.

2. Vocabulary “Base” (the Big number) “Exponent”

3. What does an exponent tell us to do? The exponents tells us…______________________________________ So = ____________= _______ This is not the same as because that means _________ = ______ Remember that: Multiplication is a quick way to…_____________ Exponents are a quick way to…________________ How many times to multiply the base by itself (4)(4)(4)(4)(4) 1,024 4+4+4+4+4 20 Do Addition Do Multiplication

4. Practice Means…(8)(8) = 64 Means…(5)(5)(5) = 125 Means…(3)(3)(3)(3) = 81 Means…(10)(10)(10)(10)(10)(10) = 1,000,000 Means…(12) = 12 Means…(2)(2)(2)(2)(2)(2)(2)(2)(2)(2) = 1,024 Try the rest of the practice with your team!

5. Make a prediction… What is the value of any number with an exponent of 0? Explain. Example: What is 2 0 ?

6. Follow the pattern to determine the solution to 2 0 ! Find the pattern… Pattern: Divide the previous number in standard form by the base (2). = ___________ = ________

7. = ___________ Follow the pattern to determine the solution to 10 0 ! Find the pattern… Pattern: Divide the previous number in standard form by the base (10). = ___________ Any base with an exponent of 0 is equal to 1!

8. Reflection Harry believes that 9 2 = 18. Is he correct? If not explain to Harry how to correct his error.
