1
Using Exponents to Write Large Numbers By Monica Yuskaitis

2
For Learning to Happen! Clear your desk of anything that may distract you. Remove all other thoughts from your mind. Pay close attention. Try all the examples. Ignore all other distractions.

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

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

5
Multiplying Multiples of Ten Multiply These Numbers 100 x 2 = 1,000 x 3 = 10,000 x 7 = 100,000 x 9 = 200 3,000 70,000 900,000

6
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 = 1,000 x 3 = 10,000 x 7 = 100,000 x 9 = 200 3,000 70,000 900,000

7
Short Cut for Writing Large Numbers Combine these two steps for writing large numbers. 6 x 10 2 = 6 x (10 x 10) = 6 x 100 = 600 600

8
Short Cut for Writing Large NumbersRemember! The exponent is the same as the number of zeros. 6 x 10 2 = 600

9
What is the Standard Number? 7 x 10 2 = 700

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

11
What is the Standard Number? 9 x 10 4 = 90,000

12
What is the Standard Number? 4 x 10 2 = 400

13
What is the Exponent Form? 5 x 10 2 = 500

14
What is the Exponent Form? 6 x 10 3 = 6,000

15
What is the Exponent Form? 9 x 10 4 = 90,000

16
What is the Exponent Form? 7 x 10 5 = 700,000
