You can rewrite this equation such that $$x$$ is a fixed point of $$f(x)$$, that is $$x=f(x)$$:

$$x=\frac{3}{LOG(x)}$$

Then you can iterate the following program with a starting value, say $$x=4$$:
Code:
001-  43  13 :    LOG 002-       3 :    3 003-      34 :    x<>Y 004-      10 :    ÷

From then on the result flips between these last two values.
