1. The problem statement, all variables and given/known data State and prove a natural generalization of "prove that for any three positive real numbers x1, x2, x3, x1/x2 + x2/x3 + x3/x1 [itex]\geq[/itex] 3. 2. Relevant equations AG Inequality is used in subproof (x1/x2 + x2/x3 + x3/x1 [itex]\geq[/itex] 3) 3. The attempt at a solution I don't know what the book means exactly by a "natural generalization". Does it want me to prove the original AG Inequality or relate it somehow to this specific instance of the AG Inequality?
