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 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 mean? 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

“nth” power

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
