## Main Question or Discussion Point

Obviously, if you wanted to express 500,000 in Scientific Notation, you would get:

5 x 10^5

My question is, what if you were asked to express 570,098?

Move the decimal 5 places to the left, and you'd get 5.70098. Apply Scientific Notation, and you get

5.70098 x 10^5

However, this expression actually contains MORE numbers than the original number, which is not the goal of Scientific Notation.

So is SN just for expressing

Thanks a lot.
