Students will: Write expressions using Negative Exponents Evaluate numerical expressions containing negative exponents You will need pencil, paper and math textbook
5
Negative Exponent Positive Exponent
6
Negative Exponent Positive Exponent
7
Expanded Form Standard Form 10 = 10 x 10 x 10 1,000 10 = 10 x 10 100
= 10 Dividing by 10
8
Copy these two examples
Method 1 Quotient of Powers Method 2 Definition of Power Since cannot have two different values, you can conclude that
10
Example 1 Write as Positive Exponents
11
We have to know how to write
exponents as positive and negative and go from one to the other
15
Example 2: Use Negative Exponents

Example 3: Use Exponents to solve a Problem
A molecule of water contains two hydrogen atoms and one oxygen atom. A hydrogen aton is only centimeter in diameter. Write the decimal as a fraction and as a power of 10 The digit 1 is in the 100-millionths place (look beside our clock)
36
Write the decimal as a fraction 0.00000001 = 100,000,000 = 10
