Q: How is the number 24,622,041 written in Scientific Notation?
A: 2.4622041 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 24,622,041 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: | 2 | . | 4 | 6 | 2 | 2 | 0 | 4 | 1 |
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 = 2.4622041
b = 7
Now the whole thing:
2.4622041 x 107
Check your work:
107 = 10,000,000 x 2.4622041 = 24,622,041
24,622,039 | 24,622,040 | 24,622,042 | 24,622,043 |
2.4622039 x 107 | 2.462204 x 107 | 2.4622042 x 107 | 2.4622043 x 107 |
