Q: How is the number 62,650,436 written in Scientific Notation?
A: 6.2650436 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 62,650,436 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: | 6 | . | 2 | 6 | 5 | 0 | 4 | 3 | 6 |
| 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 = 6.2650436
b = 7
Now the whole thing:
6.2650436 x 107
Check your work:
107 = 10,000,000 x 6.2650436 = 62,650,436
| 62,650,434 | 62,650,435 | 62,650,437 | 62,650,438 |
| 6.2650434 x 107 | 6.2650435 x 107 | 6.2650437 x 107 | 6.2650438 x 107 |
