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
