1 Exponents

2 Location of Exponent An exponent is a little number high and to the right of a regular or base number. 3 4 Exponent Base

3 Definition of Exponent
An exponent tells how many times a number is multiplied by itself. 3 4 Exponent Base

4 What an Exponent Represents
An exponent tells how many times a number is multiplied by itself. 4 = 3 x 3 x 3 x 3 3

5 How to read an Exponent This exponent is read three to the fourth power. 3 4 Exponent Base

6 How to read an Exponent This exponent is read three to the 2nd power or three squared. 3 2 Exponent Base

7 How to read an Exponent This exponent is read three to the 3rd power or three cubed. 3 3 Exponent Base

8 Read These Exponents 3 2 6 7 2 3 5 4

9 What is the Exponent? 3 2 x 2 x 2 = 2

10 Any number to the 1st power equals that number.
6¹ = 6

11 Any number to the zero power equals one.
8º = 1 4º = 1 2005º = 1

12 What is the Exponent? 2 3 x 3 = 3

13 What is the Exponent? 4 5 x 5 x 5 x 5 = 5

14 What is the Base and the Exponent?
4 8 x 8 x 8 x 8 = 8

15 What is the Base and the Exponent?
5 7 x 7 x 7 x 7 x 7 = 7

16 What is the Base and the Exponent?
9 2

17 How to Multiply Out an Exponent to Find the Standard Form
4 3 = 3 x 3 x 3 x 3 9 27 81

18 What is the Base and Exponent in Standard Form?
2 4 16 =

19 What is the Base and Exponent in Standard Form?
3 2 8 =

20 What is the Base and Exponent in Standard Form?
1 3 3 =

21 What is the Base and Exponent in Standard Form?
5 1 =

22 Exponents Are Often Used in Area Problems to Show the Feet Are Squared
Length x width = area A pool is a rectangle Length = 30 ft. Width = 15 ft. Area = 30 x 15 = 450 ft. 15ft. 30ft 2

23 Length x width x height = volume A box is a rectangle Length = 10 cm.
Exponents Are Often Used in Volume Problems to Show the Centimeters Are Cubed Length x width x height = volume A box is a rectangle Length = 10 cm. Width = 10 cm. Height = 20 cm. Volume = 20 x 10 x 10 = 2,000 cm. 20 10 10 3

24 Here Are Some Areas Change Them to Exponents
40 feet squared = 40 ft. 56 sq. inches = 56 in. 38 m. squared = 38 m. 56 sq. cm. = 56 cm. 2 2 2 2

25 Here Are Some Volumes Change Them to Exponents
3 30 feet cubed = 30 ft. 26 cu. inches = 26 in. 44 m. cubed = 44 m. 56 cu. cm. = 56 cm. 3 3 3

26 Exponents of Ten Notice that the number of zeros matches the exponent number 2 100 10 3 1,000 4 10,000 5 100,000

27 What Is the Standard Form
Exponents of Ten What Is the Standard Form of These Tens? 2 100 10 3 1,000 4 10,000 5 100,000

28 Multiplying Multiples of Ten
Multiply These Numbers 100 x 2 = 200 1,000 x 3 = 3,000 10,000 x 7 = 70,000 100,000 x 9 = 900,000

29 Multiplying Multiples of Ten
Did you notice that all you have to do is multiply 1 x whole number & add the zeros behind? 100 x 2 = 200 1,000 x 3 = 3,000 10,000 x 7 = 70,000 100,000 x 9 = 900,000

30 Short Cut for Writing Large Numbers
Combine these two steps for writing large numbers. 6 x 10 2 600 = 6 x (10 x 10) = 6 x 100 = 600

31 Short Cut for Writing Large Numbers
Remember! The exponent is the same as the number of zeros. 2 6 x 10 600 =

32 What is the Standard Number?
7 x 10 2 700 =

33 What is the Standard Number?
8 x 10 3 8,000 =

34 What is the Standard Number?
9 x 10 4 90,000 =

35 What is the Standard Number?
4 x 10 2 400 =

36 What is the Exponent Form?
5 700,000 7 x 10 =

37 What is the Exponent Form?
2 500 5 x 10 =

38 What is the Exponent Form?
3 6,000 6 x 10 =

39 What is the Exponent Form?
4 90,000 9 x 10 =
