(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

prove the following inequality:

2. Relevant equations

[tex]\frac{a^4+b^4+c^4}{a^2b^2+a^2c^2+b^2c^2}\geq\frac{2u+3\lambda}{3(u+\lambda)}[/tex]

for all the reals a,b,c different from zero and for all the natural u,λ

3. The attempt at a solution

induction i think in this case will make things worst
