# Q: How is the number 398,545 written in Scientific Notation?

A: 3.98545 x 10

^{5}
A: 3.98545 x 10^{5}

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 10 ^{b}**

Follow the steps below to see how 398,545 is written in scientific notation.

To find **a**, take the number and move a decimal place to the right one position.

- Original Number: 398,545
- New Number: 3.98545

Now, to find **b**, count how many places to the right of the decimal.

New Number: | 3 | . | 9 | 8 | 5 | 4 | 5 |

Decimal Count: | 1 | 2 | 3 | 4 | 5 |

There are **5** 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 10 ^{b}**

**a** = 3.98545

**b** = 5

Now the whole thing:

**3.98545 x 10 ^{5}**

Check your work:

10^{5} = 100,000 x 3.98545 = **398,545**
