2. 7.3-MULTIPLYING EXPONENTS What is an exponent? = 3333 Exponent Base Base - Tells you what # you multiply. Exponent - Tells you how many times you multiply

3. What if we multiply two exponents with the same base ? = 333333333 How many 3’s do we have now? 9 So the base is 3 and the exponent is 9. 3 9 Exponent Base

4. = 333333333 What do you notice about the exponents? What does 4 + 5 = ? 9 When multiplying exponents, we can: 1.) Keep the base number and 2.) Add the exponents. Oh, I see!

6. Type 1: Simplify: 3+5  Keep the base  Add the exponents 3+6  Keep the base  Add the exponents Type 2:

7. You try: Simplify: 6+4  Keep the base  Add the exponents 5+9  Keep the base  Add the exponents

8. Type 3: Simplify: 2.) Keep the base number (or variable) 3.) Add the exponents. y 2+4 1.) Multiply the numbers in front. 4●3 =

9. You try: Simplify: a 5 + 3 2424 = = 8 a 8 1.) Multiply the numbers in front. 2.) Keep the base number (or variable) 3.) Add the exponents.

10. Type 4: Simplify: 2.) Keep the common base number (or variable) 3.) Add the exponents. x 1+3 1.) Multiply the numbers in front. 5●25●2 = 1 4.) Keep the common base number (or variable) y 5.) Add the exponents. 3+6

11. Try this: Simplify: 2.) Keep the common base number (or variable) 3.) Add the exponents. x 4+2 1.) Multiply the numbers in front. 4●44●4 = 4.) Keep the common base number (or variable) y 5.) Add the exponents. 3+5
