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 601,112,160 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 | . | 0 | 1 | 1 | 1 | 2 | 1 | 6 | 0 |
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 = 6.0111216 (Please notice any zeroes on the end have been removed)
b = 8
Now the whole thing:
6.0111216 x 108
Check your work:
108 = 100,000,000 x 6.0111216 = 601,112,160
601,112,158 | 601,112,159 | 601,112,161 | 601,112,162 |
6.01112158 x 108 | 6.01112159 x 108 | 6.01112161 x 108 | 6.01112162 x 108 |
