    Thanks! combine with your method, I finally have a 34 bytes solution:
    ::a::x=math.log(C,x)print(x)goto a


Nice!  You are the first person posted a solution.
And I should note that it was Dirk who has solved the mathematical half of the task.
BTW, my own program was longer than 34 bytes because I wasn't aware of the idea of using non-initialized X. 


But this is not the end of the story.
There is a bonus task: *"dijkstrify" the code*
Edsger Dijkstra considered "goto" statement harmful.
Rewrite the code preserving its length of 34 bytes but without using "goto". 



::a::x=math.log(C,x)print(x)goto a
repeat x=math.log(C,x)until print(x)

uh well, 2 bigger. I tried.
