11.03 Scientific Notation |
|
|
| Learning
Outcomes: The student will:
| Change a number to scientific notation |
843 000 000 = 8.43 x
108 843 000 = 8.43
x 105
843 = 8.43 x 102
84.3 = 8.43 x 101
8.43 = 8.43 x 100 |
Scientific notation is a product
of a number between 1 and 10 and a power of
10. |
| Change scientific notation to a number |
5.69 x 100 = 5.69 5.69 x 101 = 56.9
5.69 x 102 = 569
5.69 x 103 = 5690
5.69 x 104 = 56 900 |
Scientific notation is a product of a number between 1 and 10 and a power
of 10. |

Review:
Scientific notation has the following
form:
N X 10x
where N is a number greater than
1 but less than 10 and
x is an
exponent of 10.
Scientific notation is a convenient way of writing very large or very
small numbers:
| Standard Form |
Scientific Notaton |
| 153 000 000 000 000 |
1.53 x 1014 |
| 49 000 000 000 000 000 000 |
4.9 x 1019 |
| 93 000 000 |
