Q: How is the number 53,104,609 written in Scientific Notation?
A: 5.3104609 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 53,104,609 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 | . | 3 | 1 | 0 | 4 | 6 | 0 | 9 |
| 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 = 5.3104609
b = 7
Now the whole thing:
5.3104609 x 107
Check your work:
107 = 10,000,000 x 5.3104609 = 53,104,609
| 53,104,607 | 53,104,608 | 53,104,610 | 53,104,611 |
| 5.3104607 x 107 | 5.3104608 x 107 | 5.310461 x 107 | 5.3104611 x 107 |
