Q: How is the number 153,005,529 written in Scientific Notation?
A: 1.53005529 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 153,005,529 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 | . | 5 | 3 | 0 | 0 | 5 | 5 | 2 | 9 |
| 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 = 1.53005529
b = 8
Now the whole thing:
1.53005529 x 108
Check your work:
108 = 100,000,000 x 1.53005529 = 153,005,529
| 153,005,527 | 153,005,528 | 153,005,530 | 153,005,531 |
| 1.53005527 x 108 | 1.53005528 x 108 | 1.5300553 x 108 | 1.53005531 x 108 |
