Exponents. Question: What are exponents and when will I have to use them?

Definitions: Exponent – Is the number that tells us how many times to multiply a number (called the base) by itself. Base – Is a number that is multiplied.

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

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

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, Do Addition Do Multiplication

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!

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

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). = ___________ = ________

= ___________ 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!

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