1. Lesson 9.4 Page 500 Negative Exponents

2. Students will: Write expressions using Negative Exponents Evaluate numerical expressions containing negative exponents You will need pencil, paper and math textbook

5. Copy these two examples Method 1 Quotient of Powers Method 2 Definition of Power Since cannot have two different values, you can conclude that

7. Example 1 Write as Positive Exponents

24. 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 0.00000001 centimeter in diameter.

25. 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 0.00000001 centimeter in diameter. Write the decimal as a fraction and as a power of 10

26. 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 0.00000001 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)

27. 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 0.00000001 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) Write the decimal as a fraction 0.00000001 = 100,000,000 = 10 Definition of a negative exponent
