A place to air possible concerns or difficulties in understanding ProjectEuler problems. This forum is not meant to publish solutions. This forum is NOT meant to discuss solution methods or giving hints how a problem can be solved.
As your posts will be visible to the general public you
are requested to be thoughtful in not posting anything
that might explicitly give away how to solve a particular problem.
This forum is NOT meant to discuss solution methods for a problem.
In particular don't post any code fragments or results.
Don't start begging others to give partial answers to problems
Don't ask for hints how to solve a problem
Don't start a new topic for a problem if there already exists one

There's an error in the problem statement. It currently says
the denominator is a power of 3 i.e. $b=3^k, k>0$.
It should say
the denominator is a power of 3 other than 1, i.e. $b=3^k, k>0$.
(The other possible correction, $>$ to $\ge$, doesn't match up with the test cases).
