Q: How is the number 24,603,779 written in Scientific Notation?
A: 2.4603779 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 24,603,779 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 | 0 | 3 | 7 | 7 | 9 |
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 = 2.4603779
b = 7
Now the whole thing:
2.4603779 x 107
Check your work:
107 = 10,000,000 x 2.4603779 = 24,603,779
24,603,777 | 24,603,778 | 24,603,780 | 24,603,781 |
2.4603777 x 107 | 2.4603778 x 107 | 2.460378 x 107 | 2.4603781 x 107 |
