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

Why do these 2 examples have
parentheses?
1). 9 • 9 • 9 • 9
