  1. Multiplication and Division of Powers • We will often want to be able to multiply and divide powers that have the same base. • An example of Multiplication of Powers • An example of Division of Powers

  2. Consider the following multiplication of powers: • This suggests the property for the Multiplication of Powers. Let b represent a real number and m and n represent positive integers. Then …

  3. Consider the following division of powers: • This suggests the property for the Division of Powers. Let b represent a real number and m and n represent positive integers. Then …

  4. Example 1 Both bases are the same, so apply the property of multiplication of powers:

  5. Example 2 Since the bases are not the same, we cannot use the property of multiplication of powers.

  6. Example 3 Both bases are the same, so apply the property of multiplication of powers:

  7. Example 4 Both bases are the same, so apply the property of division of powers:

  8. Example 5 Both bases are the same, so apply the property of division of powers:

  9. Example 6 This problem uses both of the properties. Note that all of the bases are the same. First apply the multiplication property in the numerator:

  10. Now apply the division property:

  11. Example 7 Note that all of the bases are the same. First apply the multiplication property in the denominator:

  12. Now apply the division property:
