Once a solution is found mod 5, extend it to mod 25 using lifting techniques. Though full application requires deeper number theory, the idea is to test values of the form $n = 5k + 2$ and find $k$ such that $ (5k+2)^3 \equiv 13 \pmod{25} $. Expanding and simplifying reveals valid $k$ that satisfy the congruence.

Yes. By number theory, since 125 is a prime power ($5^3$), cubic congruences have solutions under certain conditions, especially when prime divisors match structure. While existence isn’t guaranteed for every residue, detailed analysis confirms at least one solution exists.

Repeat the process: test values $n = 25m + r$ (where $r = 2, 7, 12,\dots$ from searching mod 25) to land on solutions satisfying $n^3 \equiv 13 \pmod{125}$. This manual search, though tedious, is feasible due to the small modulus and known residue patterns.
