Question

How do you write `204,500` in scientific notation?

Answer 1

`204,500 = 2.045 xx 10^5`

Explanation:

`100,000` is the 5th power of 10 which can be written as:

`100,000 = 10^5`

`200,000 = 2 xx 10^5`

We have a bit more than exactly `200,000`

`204,500 = 2.045 xx 10^5`

In standard form (also called scientific notation), there is always only ONE digit before the decimal point.
