Does the base-10 representation of $2^n$ contain all 10 digits for all sufficiently large integerintegers $n$?

Does the base-10 representation of $2^n$ contain all 10 digits for all sufficiently large integer $n$?


In general, let $x_{k}$ denote the base-$k$ representation of the positive integer $x$. We say $x$ is k$k$-powerful if $x^n_{k}$ contains all of the $k$ digits for all sufficiently large integer nintegers $n$.

For example, it's easy to check that 2 is 2-powerful, but 3 is not 3-powerful. The title question asks whether 2 is 10-powerful.

For any given $x$ and $k$, can we decide if $x$ is k$k$-powerful?

In general, let $x_{k}$ denote the base-$k$ representation of the positive integer $x$. We say $x$ is k-powerful if there exists $n_0$ such that for any integer $n\gt n_0,x^n_{k}$$x^n_{k}$ contains all of the $k$ digits for all sufficiently large integer n.
