Q: How is the number 36,951,827 written in Scientific Notation?
A: 3.6951827 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 36,951,827 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 | . | 6 | 9 | 5 | 1 | 8 | 2 | 7 |
| 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 = 3.6951827
b = 7
Now the whole thing:
3.6951827 x 107
Check your work:
107 = 10,000,000 x 3.6951827 = 36,951,827
| 36,951,825 | 36,951,826 | 36,951,828 | 36,951,829 |
| 3.6951825 x 107 | 3.6951826 x 107 | 3.6951828 x 107 | 3.6951829 x 107 |
