Q: How is the number 65,562,064 written in Scientific Notation?
A: 6.5562064 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 65,562,064 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 | . | 5 | 5 | 6 | 2 | 0 | 6 | 4 |
| 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 = 6.5562064
b = 7
Now the whole thing:
6.5562064 x 107
Check your work:
107 = 10,000,000 x 6.5562064 = 65,562,064
| 65,562,062 | 65,562,063 | 65,562,065 | 65,562,066 |
| 6.5562062 x 107 | 6.5562063 x 107 | 6.5562065 x 107 | 6.5562066 x 107 |
