1 Exponents

2 For Learning to Happen! Exponents
Remove all other thoughts from your mind. Pay close attention to this lesson. Try all of the examples. Ignore all other distractions.

3 Exponents An exponent is a little number high and to the right of a regular or base number. 3 8 Exponent Base

4 8 This exponent is read 8 to the 3rd power, or 8 cubed. 3 Exponent
Exponents This exponent is read 8 to the 3rd power, or 8 cubed. 3 8 Exponent Base

5 8 An exponent tells how many times a number is multiplied by itself. 3
Exponents An exponent tells how many times a number is multiplied by itself. 3 8 Exponent Base

6 Exponents This exponent means 8•8•8 = 512 3 8 Exponent Base

7 6 This exponent is read six to the fourth power. 4 Exponent Base
Exponents This exponent is read six to the fourth power. 6 4 Exponent Base

8 3 This exponent is read three to the 2nd power or three squared. 2
Exponents This exponent is read three to the 2nd power or three squared. 3 2 Exponent Base

9 Exponents Read These Exponents 2 7 7 to the 2nd power or 7 squared

10 Exponents Read These Exponents 3 10 10 to the 3rd power or 10 cubed

11 Exponents What is the Exponent? 3 2 • 2 • 2 = 2

12 Exponents What is the Exponent? 4 a a • a • a • a =

13 (bc)(bc)(bc) = (bc) What is the Exponent? 3 Exponents
NOTICE that you keep the parenthesis around the variables (bc) because you are cubing all the (bc)

14 Write the Verbal Phase Power Verbal Phrase Means Exponents
“Seven to the 2nd power” “Seven squared” “Five to the 3rd power” “Five cubed”

15 Write the Verbal Phase Power Verbal Phrase Meaning Exponents
“Nine to the 4th power” “Two to the 5th power”

16 How to Multiply Out Exponents
= 3 • 3 • 3 • 3 4 3 9 27 81

17 How to Multiply Out Exponents
= 2 • 2 • 2 • 2 • 2 5 2 4 8 16 32

18 62 –62 = –6•6 = -36 (-6)2 -(6)2 1 Exponents
When simplifying exponents you must watch the sign and the parenthesis! 62 = 6•6 –62 = –6•6 = 36 = -36 (-6)2 =(-6)(-6) -(6)2 = - (6)(6) = 36 1 = -36

19 32a3 An exponent is written in exponential form when it is simplified.
Exponents An exponent is written in exponential form when it is simplified. Exponential Form 32a3

20 Exponents An exponent is written in factor form when it is written out. Factor Form 32a3 = 3•3•a•a•a

21 x • 8 • y • 8 • x 82x2y 2a2b1 a • b • a • 2 13 p p p r r 13p3r2
Exponents Factored Form Exponential Form x • 8 • y • 8 • x 82x2y 2a2b1 a • b • a • 2 13 p p p r r 13p3r2

22 Exponents Factored Form Exponential Form 5 • x • x • x 5x3 (5x)(5x)(5x) (5x)3 = 53x3 = 125x3

23 Exponents Factored Form Exponential Form 8(ab)(ab) 8(ab)2 = 8a2b2 (4xwy)(4xwy)(4xwy) = 43x3w3y3 (4xwy)3 = 64x3w3y3

24 Exponents Evaluate the expression if x = 3 and y = 4 “Evaluate” mean to solve!

25 Exponents Evaluate the expression if x = 3 and y = 4 “Evaluate” mean to solve!

That’s all folks

30 8 3 8•8•8 = 512 #1 Exponent Base 32a3 2x2y1 Exponents Factored Form
An exponent tells how many times a number is multiplied by itself. 3 8 Exponent 8•8•8 = 512 Base Factored Form Exponential Form 3 • 3 • a • a • a 32a3 x • y • x • 2 2x2y1

31 52 –52 = – (5)•(5) = –25 (-5)2 –(5)2 1 # 2 Simplifying Powers
When simplifying exponents you must watch the sign and the parenthesis! 52 = 5•5 –52 = – (5)•(5) = 25 = –25 (-5)2 =(-5)(-5) = - (5)(5) –(5)2 = –25 = 25 1

32 ^ 5 4 = 625 5 4 = 625 5 4 5 = 625 4 = 625 #3 Evaluate The Power
1) 2) 3) 4) #3 Evaluate The Power To find 54 on my calculator I type in 5 ^ 4 = 625 5 4 = 625 xy 5 4 5 = 625 x 4 = 625 yx Circle the method that works on your calculator!

33 TEACHER NOTE: The lesson above was taught for Pre-Algebra & Algebra
TEACHER NOTE: The lesson above was taught for Pre-Algebra & Algebra. The following slides were used for the class of Algebra Readiness (lower level students) and slide #18-28 were taken out of the lesson above since we were just introducing Exponents.

34 Exponents Evaluate the Power “Evaluate” mean to solve! 1) 2) 3) 4)

35 Addition: Exponents Multiplication: -One-Dimensional Growth 3 4
“Three added to four” + = 3 4 + = 7 units Multiplication: Two-Dimensional Growth “Three times four” or “Three groups of four” + + = 4 4 4 3(4) 12 square units + + = =

36 Exponents: Exponents Three-Dimensional Growth
“Three to the third power” “Three to the fourth power” 3 3 3

37 Exponents P = s+s+s+s P = 4s One Dimensional Two Dimensional Three
Perimeter Volume Area 5 5 5 5 5 5 5 5 5 P = s+s+s+s P = 4s “Five Squared” “Five Cubed” One Dimensional Two Dimensional Three Dimensional

38 Exponents The End!!! I am going to give you a Study Guide (blue).
Please take good notes on what we just learned! You can use these notes to help you with homework! You can use these notes on your test! That’s all folks

39 3 Exponents & Powers 4 Exponent Base #1
An exponent or power tells how many times a number is multiplied by itself. 4 Exponent 3 Base “Five to the 2nd power” “Five squared” “Seven to the 3rd power” “Seven cubed”

40 ^ 5 4 = 625 5 4 = 625 5 4 5 = 625 4 = 625 #2 Evaluate The Power
1) 2) 3) 4) #2 Evaluate The Power To find 54 on my calculator I type in 5 ^ 4 = 625 5 4 = 625 xy 5 4 5 = 625 x 4 = 625 yx Circle the method that works on your calculator!
