Significant Digits and Scientific Notation:Determine the number of significant digits in each number and write out the specific significant digits.

Significant Digits and Scientific Notation

Part 1: Determine the number of significant digits in each number and write out the specific significant digits.

 

1. 405000 = 3 significant digits – 4,0,5

 

 

2. 0.0098 = 2 significant digits – 9,8

 

 

3. 39.999999 = 8 significant digits – 3,9,9,9,9,9,9,9

 

 

4. 13.00 = 4 significant digits – 1,3,0,0

 

 

5. 80,000,089 = 8 significant digits – 8,0,0,0,0,0,8,9

 

 

6. 55,430.00 = 7 significant digits – 5,5,4,3,0,0,0

 

 

7. 0.000033 = 2 significant digits – 3,3

 

 

8. 620.03080 = 8 significant digits – 6,2,0,0,3,0,8,0

 

Part 2: Write the numbers below in scientific notation, incorporating what you know about significant digits.

 

1. 70,000,000,000 = 7 x 10^10

 

2. 0.000000048 = 4.8 x 10^-8

 

3. 67,890,000 = 678.9 x 10^5

 

4. 70,500 = 70.5 x 10^3

 

5. 450,900,800 = 450900.8 x 10^3

 

6. 0.009045 = 904.5 x 10^-5

 

7. 0.023 = 2.3 x 10^-2
