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 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 5 copies of 3 3+3+3+3+3 5X3 • What would 3 with itself 5 times, look like? • What do both of the previous slides have in common? Is there any correspondence between them? What does 9 7 mean? 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 “nth” power ARE THESE WRITTEN CORRECTLY? •5 = 5x5x5x5x5x5 • 97 x 97 x 97 x 97 = 97 • (-2) = (-2)• (-2) •(-2) WHAT ABOUT THESE? 3.8 = 3.8 • 3.8 • 3.8 • 3.8 • 3.8 -4 11 -4 11 -4 11 Why do these 2 examples have parentheses? 1). 9 • 9 • 9 • 9 7 7 7 7 2). -4 • 4 • -4 11 11 11 = 9 7 = -4 11
