Question

How do you write `360 000 000` in scientific notation?

Answer 1

`3.6*10^8`

Explanation:

The number has to be changed to contain 1 significant figure.
Count the number of zeros and put it in terms of 10^_.

Eg: `100=10^2`, `10000000000=10^10`

`360000000=36*10^7`

This is in 2 significant figures.
Change this to 1 significant figure, and multiply another power of 10.

`3.6*10^8`
