Question: Algebra - variables as exponents. How do I format in a way maple can solve?

Can someone please explain the error I am making in the input syntax?

Somehow my input is causing maple to be unable to solve these equations.

 


*edit* i'm also getting the same result for something like:

ln(x)=-3.86

I don't understand the empty brackets, is maple telling me there's no solution, or is something wrong with my syntax? I have to be doing something wrong here, but i just don't see it yet.

 

Please Wait...
