Q: How is the number 134,010,530 written in Scientific Notation?
A: 1.3401053 x 108
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 134,010,530 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 | . | 3 | 4 | 0 | 1 | 0 | 5 | 3 | 0 |
| Decimal Count: | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
There are 8 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 = 1.3401053 (Please notice any zeroes on the end have been removed)
b = 8
Now the whole thing:
1.3401053 x 108
Check your work:
108 = 100,000,000 x 1.3401053 = 134,010,530
| 134,010,528 | 134,010,529 | 134,010,531 | 134,010,532 |
| 1.34010528 x 108 | 1.34010529 x 108 | 1.34010531 x 108 | 1.34010532 x 108 |
