    If you just want a final answer, use the Prime Number Theorem.

    What can you say about $2^n/log(2^n)$ ?

    This is sequence $A007053$ at $OEIS$. Have a look at the second plot (if still required after Yves Daoust's comments)

    Here's a direct link: oeis.org/A007053 Almost anything about number theory, the OEIS is sure to have something directly on point or at least relevant.
