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.
