  What is the f? Is it multiplied like this? 1/(E4*f) or 1/E4f

  IT doesn't give f. I'll tell you again, :| e^-4f Thats a negative 4 exponent.

  Thats the question, but the answer I got was 1/e to the fourth power, f.

  That's ok; however, you still are not writing it clearly. e^-4f can mean (e^-4)*f or it can mean e^(-4f). If the former, it's the first answer I gave you. If the latter, it's the second answer. Also, E and e aren't the same.

  I believe I have to times f, Sorry for not writing it carefully, this keyboard is crap. e^-4*f I got 1/e^4*f or just 1/e^4f? Also, please give me a webpage and responde as quickly as possible, I've been on Jishka for an hour ):

  Here is a site. The last item on the menu talks about negative exponents. I think the answer is 1/e4f or 1/E4f depending upon the original problem being E or e.
