Q: How is the number 3,579,867 written in Scientific Notation?
A: 3.579867 x 106
The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.
Calculating scientific notation for a positive integer is simple, as it always follows this notation:
a x 10b
Follow the steps below to see how 3,579,867 is written in scientific notation.
To find a, take the number and move a decimal place to the right one position.
Now, to find b, count how many places to the right of the decimal.
| New Number: | 3 | . | 5 | 7 | 9 | 8 | 6 | 7 |
| Decimal Count: | 1 | 2 | 3 | 4 | 5 | 6 |
There are 6 places to the right of the decimal place.
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 3.579867
b = 6
Now the whole thing:
3.579867 x 106
Check your work:
106 = 1,000,000 x 3.579867 = 3,579,867
