In general, the mth qualifying number (counting 38 as the zeroeth such number) of the form (n-1)^(1/(n-1)) has the form (as string):
"1.(m zeroes)1(m+2 zeroes)1"; since the last part is so small it can be considered as 1;
1.1001, 1.010001, 1.00100001, 1.0001000001, etc.
This is the form 1+1/(10^(m+1))+1/(10^(2m+4)).
So the function (1+1/(10^(m+1))+1/(10^(2m+4)))^(N-1)+1 = N returns n as the integer part of N.
When m=5, N=16626518.569717461698..., so n = 16626518.
When m=6, N=190660035.08011929935..., so n = 190660035.
When m=7, N= 2148818406.4441059949..., so n= 2148818406.
and so on. |
