Q: How is the number 94,410,193 written in Scientific Notation?
A: 9.4410193 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 94,410,193 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 | 4 | 1 | 0 | 1 | 9 | 3 |
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 = 9.4410193
b = 7
Now the whole thing:
9.4410193 x 107
Check your work:
107 = 10,000,000 x 9.4410193 = 94,410,193
94,410,191 | 94,410,192 | 94,410,194 | 94,410,195 |
9.4410191 x 107 | 9.4410192 x 107 | 9.4410194 x 107 | 9.4410195 x 107 |
