To
Change from Standard Form to Scientific Notation:
| (1) |
Place
decimal point such that there is one non-zero digit to the left
of the decimal point.
|
| (2) |
Count number
of decimal places the decimal has "moved" from the
original number. This will be the exponent of the 10.
|
| (3) |
If the
original number was less than 1, the exponent is negative; if
the original number was greater than 1, the exponent is
positive.
|
Examples:
|
Given:
4,750,000 |
| use: |
4.75 (moved
6 decimal places) |
|
answer:
4.75 X 106 |
The
original number was greater than 1 so the exponent is positive. |
|
Given:
0.000789 |
| use: |
7.89 (moved
4 decimal places) |
|
answer:
7.89 x 10-4 |
The
