Question

How do you write 543.621 in scientific notation?

Answer 1

`color(green)("Another way of thinking about it!")`

Explanation:

Keep the decimal point stationary but slide the number until you end up with `5*43621`

This is not the same value we started with so we need to convert back. We do this by multiply it by `10xx10 =10^2`

`color(green)("(we moved the number 2 places, hence " 10^2)")"`

So `5*43621 xx 10^2 = 543*621`

Thus writing `543*621` in Scientific Notation gives `5*43621xx10^2`
