Q: How is the number 204,610,041 written in Scientific Notation?
A: 2.04610041 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 204,610,041 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 | . | 0 | 4 | 6 | 1 | 0 | 0 | 4 | 1 |
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 = 2.04610041
b = 8
Now the whole thing:
2.04610041 x 108
Check your work:
108 = 100,000,000 x 2.04610041 = 204,610,041
204,610,039 | 204,610,040 | 204,610,042 | 204,610,043 |
2.04610039 x 108 | 2.0461004 x 108 | 2.04610042 x 108 | 2.04610043 x 108 |
