Q: How is the number 50,004,452 written in Scientific Notation?
A: 5.0004452 x 107
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 50,004,452 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: | 5 | . | 0 | 0 | 0 | 4 | 4 | 5 | 2 |
| Decimal Count: | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
There are 7 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 = 5.0004452
b = 7
Now the whole thing:
5.0004452 x 107
Check your work:
107 = 10,000,000 x 5.0004452 = 50,004,452
| 50,004,450 | 50,004,451 | 50,004,453 | 50,004,454 |
