Hi everybody,  
I’m writing a smart contract stateful in PyTeal in which I have to implement some operations, including the power and logarithm operation. It’s known that it isn’t possible to use loops in PyTeal, but which can be an arithmetic alternative to implement power and logarithm?

Thanks for all the tips!
