Scientific Notation
In class the other day, we were taught ( or reminded) how to do scientific notation. I think it looks confusing, but once you do one, it's pretty easy. Lets say you have the number 0.0804. With this number, you would have to move the decimal to the right until there is one significant figure to the left of it. So you would move the decimal two spots over, in-between the 8 and the 0 to the right of it. So the new number would be 8.04. We times this number by ten because when you move the decimal over, you are multiplying it by 10 or -10. In this case, we are multiplying it by -10 since it is moving to the right. The scientific notation of this number would be 10 x 8.04 -2 ( the two is suppose to be an exponent)

I agree, it isn't too difficult after you get used to doing it more. It comes up quite frequently too so it will be useful to know for our test tomorrow.
ReplyDeleteThis explanation helps a lot since i may have confused the exponents on the quiz, but this helps clear that up, thank you!
ReplyDeleteI also agree that it was not too difficult after reviewing it. Thanks for explaining it clearly in your post!
ReplyDeleteI like writing in scientific notation more than writing out the full number (most of the time). It just saves time, and I'm to lazy to write out all those zeros all the time. Thanks for the explanation!
