    Q: Can coding help solve this effortlessly?

  • Begin by solving simpler congruences, like $ n^3 \equiv 13 \pmod{5} $. Since $13 \equiv 3 \pmod{5}$, test integers from 0 to 4:
  • Tech professionals building or auditing encryption systems
  • $1^3 = 1$
    • 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.

  • $0^3 = 0$
