Slide 1

Exponents We are learning tosimplify expressions that contain exponents. Slide 2 Vocabulary Base (the Big number) Exponent Slide 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 Slide 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! Slide 5 Make a prediction What is the value of any number with an exponent of 0? Explain. Example: What is 2 0 ? Slide 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). = ___________ = ________ Slide 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! Slide 8 Reflection Harry believes that 9 2 = 18. Is he correct? If not explain to Harry how to correct his error.
