Homework Help: Scientific Notation

Posted by Anonymous on Friday, September 9, 2011 at 8:55pm.

Just started learning about the scientific notation, and its actually quite easy, but I dont know why im still struggling with it.

For example it says express the following measurements in scientific notation:

5800m

The answer is 5.8 * 10^3

What confuses me is that how do you know where to put the decimal thing. It can't be anywhere in the Zeros? I was also confused on how they got the power to the three thing, but I figured that you have to imagine the decimal being at the end of 5800, then you move 3 decimal places till you reach 5.8. I want to know an easier way to do this, cause I think Im thinking too much.
