Scientific Notation
How do we know when to write solutions using scientific notation? I usually do so as a default but when checking the solutions manual, I noticed that sometimes answers like (for example) .0623 is left just like that and not written as 6.23 * 10^2. Is there a reason for that? Are there specific rules to be followed when using scientific notation?

Re: Scientific Notation
I think that it's based off of personal preference. It should not matter which format you write your answer in, unless the question specifically asks you to write it a certain way.

Re: Scientific Notation
I would say scientific notation is not required except the question asks. It is a way to make your answer clear, so it is up to you to use it or not for most questions as long as you get the right result.

Re: Scientific Notation
I use scientific notation primarily when there's multiple zeros after the decimal point before getting to the exact numbers. For example, if the answer is 0.00072, I would write it in scientific notation instead of writing out all the zeros in order to get two sig figs.

Re: Scientific Notation
I had the same problem of not knowing when scientific notation is actually required. More specifically if its neccesary to do all our work in this form or can I use decimals up until reaching the final solution?

Re: Scientific Notation
It's really just personal preference. If you find it a lot easier to write out numbers especially long ones in scientific notation, you can. It's also a lot easier to use scientific notaion when you want to keep numbers at a certain sig fig.

Re: Scientific Notation
Use scientific notation in order to end the problem with the correct number of sigfigs.

If you're trying to determine whether or not you want to use scientific notation, I would recommend looking at the number of significant figures you're given. If you need to change the number of significant figures and rounding the number does not give you the correct number of significant figures, putting the answer in scientific notation might help.
