Q: How is the number 10,122,319 written in Scientific Notation?
A: 1.0122319 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 10,122,319 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: | 1 | . | 0 | 1 | 2 | 2 | 3 | 1 | 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 = 1.0122319
b = 7
Now the whole thing:
1.0122319 x 107
Check your work:
107 = 10,000,000 x 1.0122319 = 10,122,319
10,122,317 | 10,122,318 | 10,122,320 | 10,122,321 |
1.0122317 x 107 | 1.0122318 x 107 | 1.012232 x 107 | 1.0122321 x 107 |
