Investigation: Properties of Exponents
Part 1: Rewrite the mathematical expressions.
a) 43= b) 25= c) 71=
Part 2: Use expanded form to review and generalize the properties of exponents.
Step 1 Write each product in expanded form, then write it in exponential form.
a. [pic] b. [pic] c. [pic]
Step 2 Generalize your results from Step 1. (Product Property of Exponents)
[pic]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Step 3 Write the numerator and denominator of each quotient in expanded form. Reduce by eliminated common factors, and then rewrite the factors that remain in exponential form.
a. [pic] b. [pic] c. [pic]
Step 4 Generalize your results from Step 3. (Quotient Property of Exponents)
[pic]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Step 5 Write each quotient in expanded form, reduce, and rewrite in exponential form.
a. [pic] b. [pic] c. [pic]
Step 6 Now use the property you discovered in Step 4 to simplify the expressions.
a. [pic] b. [pic] c. [pic]
Step 7 Generalize your results from Steps 5 and 6. (Definition of Negative Exponents)
[pic]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Step 8 Expand each expression, and then rewrite in exponential form.
a. [pic] b. [pic] c. [pic]
Step 9 Generalize your results from Step 8. (Power of a Power Property)
[pic]
Step 10 Expand each expression, and then rewrite in exponential form. Do not multiply within the parentheses.
a. [pic] b. [pic] c. [pic]
Step 11 Generalize your results from Step 10. (Power of a Product Property)
[pic]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Step 12 Use the properties that you have discovered to simplify each expression.
a. [pic] b. [pic] c. [pic] d. [pic]
Step 13 Generalize your results from Step 12. (Zero Exponents)
[pic]
