OBJECTIVE(strategic
teaching agenda) The students will be able
to use powers and exponents in expression.
Alabama Course of Study: 6:1
VOCABULARYwrite on back of Washing Machine GO.
tells the number of times the base is used as a factor; also called an index/indicesOR exponential
notationNumber
written as a base number with an exponents (numbers expressed using exponents)
Numbers expressed using exponents
Evaluating powers (write on GO)
1. Identify and read the Power or Product.
3 to second power or 3 squared
2. Identify the base and exponent.
3. What does the power or product mean?
mulitply 3 times itself 2 times.
4. Evaluate the Power or Product.
3 x 3 = 9
baseexponent
POINTS TO REMEMBER(Write on the bottom of your GO.)
1. When no exponent is given, it is understood to be 1.
2. Any number raised to the power of 1 will always equal the number itself.
3. Any number raised to the power of 0 (except for 0) will always equal 1.
Write 45 as a product. Then find the value of the product.1. A Power; Four to the fifth power.2. 4 is the base; 5 is the exponent.3. The power means 4 times itself 5 times4. 4x4x4x4x4 =
EXAMPLE 1
Write 3 x 3 x 3 x 3 using an exponent. Then find the value of the power.
EXAMPLE 2
1. A Product; 3x3x3x3.2. 3 is the base; 4 is the exponent.3. The product means multiple 3 times itself 4 times.4. 3x3x3x3
1) 46 = 4•4•4•4•4•4 = 4096
2) 9 x 9 = 92 = 81
3) 43 = 4 • 4 • 4 = 64
4) 11 x 11 x 11= 113 = 1,331
5) 41 = 4
6) 40 = ?
Evaluate each power or product…..
