There is only one positive integer solution in the following diophantine equation Can repunits be perfect cubes?
ProveIs it true that the equation 10^{n}-9m^{3}=1$10^{n}-9m^{3}=1$ has only one positive integer solution n=m=1., namely $n=m=1$? I can't find the answer. This has an equivalent description that the repunits Rn$R_n = 11\dots1$ are not cubic numbers.
