The remainder when is divided by 5 is

🧠 Find the Cycle of Read the question. We want . The base is small, so just compute small powers and look for the cycle. , , , . So the cycle length is . To find , compute (since ). Therefore . First step: compute small powers, find the cycle, reduce the exponent modulo the cycle length. 🗺️ Working It Out Cycle of mod : — cycle length . : , so , giving . Therefore . ⚡ The Smart Move By Fermat's little theorem, for any prime and integer coprime to : . So , , etc. This gives th
