(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Give the inverse of this function

N=f(L)=18^{16-8L}

The answer has to be filled in in Maple

2. Relevant equations

3. The attempt at a solution

N=18^{16-8L}

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 this in in maple it's incorrect.

I've really no clue why it is wrong.
