Olympiad Maths Question – Smart Solution Trick

⭐ Olympiad Mathematics Question With Solution 📌 Question If x + 1/x = 3 x^3 + 1/x^3 = 18 ✔ Solution (Step-by-Step Explanation) We know the identity: Given: x + 1/x = 3 Cube both sides: (x + 1/x)^3 = 3^3 Using identity: (x + 1/x)^3 = x^3 + 1/x^3 + 3(x + 1/x) Substitute the value: 27 = x^3 + 1/x^3 + 3(3) 27 = x^3 + 1/x^3 + 9 Therefore: x^3 + 1/x^3 = 18 ⭐ Final Answer x^3 + 1/x^3 = 18 🔥 Why this is an important Olympiad trick? This question teaches how to solve cube identities without directly expanding powers. Such tricks save time in: Math Olympiad NTSE JEE / NEET School competitive tests 📝 Try Yourself (Bonus Practice) If x + 1/x = 4 Find: x^3 +1/x^3 = ? 👉 Comment your answer on our Instagram page @krmath01 📚 Follow for More Daily Problems Get daily math tricks, puzzles and Olympiad questions: 🔹 Instagram: @krmath01 🔹 Website: krmath.blogspot.com  😊
