Question

Pluto is `3.67xx10^9` miles away from the Sun. How do I write this number in standard form??

Answer 1

`3.67 xx 10^9 = 3,670,000,000` miles

Explanation:

The `xx10^color(blue)(9)` indicates how many place holders there are after the decimal point in `3.67`

So you multiply `3.67` by `1color(blue)(,000,000,000)` to get:

`3color(blue)(,670,000,000)`

The decimal point moves `9` places to the right.

A positive index of `10` indicates that it is a very number.

It the index is negative it means it is a very small decimal.
