Question

How do you express 96,470,000 using scientific notation?

Answer 1

`9.647 xx 10^7`

Explanation:

Well, expressing values in scientific notation is simply moving the decimal place behind the very first number, and keeping the significant digits.

In this case, the decimal place is behind the last `0`. Moving it left; between `9` and `6`. That's a total of 7 places to the left. Thus, you have an exponential factor of `7`.

The significant digits (in this case) are any number other than `0`. If there was context, behind the number, then we would round to decimal places until we get the same value (essentially) but with less digits.

As a result, we get:

`9.647 xx 10^7`

Hope this helps :)
