In this video, we solve a beautiful cyclic inequality from RMO 2013 (Question 4) — a classic problem for anyone preparing for Olympiad Mathematics, INMO, or high-level competitive exams. The problem states that for real numbers a, b, c, d, e greater than 1, prove that In this short explanation, I show the key insight and the inequality technique required to handle such cyclic expressions. This problem is a great example of how AM-GM inequality, Titu’s Lemma (Cauchy Engel form), or symmetry arguments can be used to get sharp lower bounds. If you are preparing for RMO, INMO, HBCSE Olympiads, JEE Mains, or want to strengthen your inequality problem-solving skills, this video will help you understand how to break down complex expressions efficiently. ✔️ Suitable for RMO / INMO aspirants ✔️ Useful for JEE Mains Advanced problem-solving ✔️ Great practice for inequality mastery ✔️ Explained step-by-step in under a minute If you enjoy Olympiad-type questions and want quick, high-quality explanations, make sure to like, share, and subscribe! #rmo #rmo2013 #inmo #matholympiad #inequality #inequalities #amgm #jeemains #jee #mathshorts #shortsmath #mathbiceps #competitionmath #olympiadprep #problem-solving #mathematics
