Q: How is the number 94,329,092 written in Scientific Notation?
A: 9.4329092 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 94,329,092 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: | 9 | . | 4 | 3 | 2 | 9 | 0 | 9 | 2 |
| 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 = 9.4329092
b = 7
Now the whole thing:
9.4329092 x 107
Check your work:
107 = 10,000,000 x 9.4329092 = 94,329,092
| 94,329,090 | 94,329,091 | 94,329,093 | 94,329,094 |
| 9.432909 x 107 | 9.4329091 x 107 | 9.4329093 x 107 | 9.4329094 x 107 |
