1. MODULE 1: LESSON 1 EXPONENTIAL NOTATION The Square of a number, is a base to the power of 2. EX: 4x4 = 4 The cube of a number, is the base to the power of 3. EX: 4x4x4 = 4

2. DO NOW With the people at your table, read the exponent packet and solve the problems. You should be discussing solutions to the items on pages 7 &8

3. 5 copies of 3 3+3+3+3+3 5X3

4. What would 3 with itself 5 times, look like?

5. What do both of the previous slides have in common? Is there any correspondence between them?

6. What does 9 mean? 7

7. EXPONENTIAL NOTATION X = (X X X X…..) n times The number X is called: X to the “nth” power. “n” is the exponent and X is the base

8. “nth” power

12. ARE THESE WRITTEN CORRECTLY ? 5 = 5 x 5 x 5 x 5 x 5 x 5 97 x 97 x 97 x 97 = 97 (-2) = (-2) (-2) (-2)

13. WHAT ABOUT THESE? 3.8 = 3.8 3.8 3.8 3.8 3.8 -4 -4 -4 11 11 11

14. Why do these 2 examples have parentheses? 1). 9 9 9 9 7 7 7 7 = 9 7 2). -4 4 -4 -4 11 11 11 = 11
