    Hmm, the attachment wouldnt open.

    But anyway the easiest way is to solve for negative exponents is to write the reciprocal of the variable with a positive exponent.

    Hi,

    I've attached an image with the solutions.

    As you may know you allways can translate the negative sign in an exponent by 1/___ . Compare my calculations.

    What about if you have (n^-2)/(n^3)? How would you simplify that? Please explain. Thnx a lot!

    Hi,

    I'm going to answer this problem - but in future do us and do yourself a favour and start a new thread:

    You know that the division of powers with the same base means that the exponents have to be subtracted:
    Code:
      n^(-2)                            1
    --------- = n^((-2)-3) = n^(-5) = ----
      n^3                             n^5

    Hello,

    it's me again:

    I send you a PDF-file with all possible formulas concerning powers and logarithm. I hope it could be helpful even in the near future.
