MODULE 1: LESSON 1EXPONENTIAL 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 do both of the previous slides have in common? Is there any correspondence between them?
EXPONENTIAL NOTATION X = (X • X • X • X…..) n times The number X is called: X to the “nth” power. “n” is the exponent and Xis the base
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)
WHAT ABOUT THESE? 3.8 = 3.8 • 3.8 • 3.8 • 3.8 • 3.8 -4 -4-4 11 11 11
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
