Q: How is the number 17,437,610 written in Scientific Notation?
A: 1.743761 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 17,437,610 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: | 1 | . | 7 | 4 | 3 | 7 | 6 | 1 | 0 |
| 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 = 1.743761 (Please notice any zeroes on the end have been removed)
b = 7
Now the whole thing:
1.743761 x 107
Check your work:
107 = 10,000,000 x 1.743761 = 17,437,610
| 17,437,608 | 17,437,609 | 17,437,611 | 17,437,612 |
| 1.7437608 x 107 | 1.7437609 x 107 | 1.7437611 x 107 | 1.7437612 x 107 |
