Lesson 1-2

EXAMPLES	Write Powers as Products
Write each power as a product of the same factor. 
1. 54 		2. 36
Five is used as a 	Three is used as a factor 
factor four times.	six times.
54 = 5  5  5  5	36 = 3  3  3  3  3  3

EXAMPLES 		Write Powers in Standard Form
Evaluate each expression.
3. 43
 43 = 4  4  4		4 is used as a factor 3 times. 
      = 64		Multiply.

4. 35
 35 = 3  3  3  3  3	3 is used as a factor 5 times.
      = 243		Multiply.

EXAMPLE  		Write Numbers in Exponential Form
5. Write 8  8  8  8  8  8  8 in exponential form.

8 is the base.  It is used as a factor 7 times.  So, the exponent is 7.
8  8  8  8  8  8  8 = 87
