Answer» HIII....... Answer: 18 Step-by-step EXPLANATION: GIVEN: x+1/x = 3 Cubing both sides (x+1/x)^3 = 3^3 Now, using the formula ( a+b)^3 x^3 + 1/x^3 + 3× x × 1/x ( x+ 1/x) = 27 x^3 + 1/x^3 + 3 (x+1/x) = 27 A/q: x+ 1/x = 3 x^3 + 1/x^3 + 3 (3) = 27 x^3 + 1/x^3 = 27-9 x^3 + 1/x^3 = 18 MARK ME AS BRAINLIST HOPE IT HELPS DO REPLY |
