the best way is to memorize up to 2^10 ... or 2^something ... then multiply it by two until your you get your result.

I realize that is not really a "mentally" way, but when you get above 2^7 that would be the way I would do it mentally.

any natural number at all? seems doubtful since this grows very large very fact. but i count on my fingers, doubling each time two four eight sixteen thirty two sixty four one twenty eight two fifty six five twelve ten twenty four it helps to be old an remember when a computer actually came with one twenty eight two fifty six or five twelve megs, so those numbers are familiar.
