A famous theorem of Hilbert (answering a question of Waring) is that for every natural number k there is some s = s(k) such that all sufficiently large integers can be written as x_1k ... x_sk, with the x_i non-negative integers. I will discuss a proof of the fact that one could, if desired, additionally insist that (for example) each x_i has only the digits 2 and 7 when written in base 10. The talk should hopefully be accessible to those without any background in analytic number theory.
