    Inverse of exponential function

    Well, this assignment was given in a little online test. The point is, that i can't see why the answer was wrong. I have 2 chances, so for the second change i will try to swap the variables.

    Inverse of exponential function

    thanks! It's also mentioned that it should be simplified as much as possible. Does that mean that the 8*LN(18) could be simplified to 8*LN(2*9) and more?

    Inverse of exponential function

    Homework Statement Give the inverse of this function N=f(L)=1816-8L The answer has to be filled in in Maple Homework Equations The Attempt at a Solution N=1816-8L 16-8L=ln(N)/ln(18) -8L=(ln(N)/ln(18))-16 L=-ln(N)/(8*ln(18))+2 Is this correct? When i fill...
