Harry J. Smith, Table of n, a(n) for n=2,...,1000

EXAMPLE

a(4) = 3 because if k = 2, 4^2 <= 2^4 but when k reaches 3, 4^3 > 2^4.

MATHEMATICA

f[n_] := (k = 1; While[n^k <= 2^n, k++ ]; Return[k]); Table[ f[n], {n, 2, 70} ]

PROG

(PARI) { for (n=2, 1000, k=1; p=2^n; while (n^k <= p, k++); write("b065801.txt", n, " ", k) ) } [From Harry J. Smith (hjsmithh(AT)sbcglobal.net), Oct 31 2009]
