Step 1
I guess there's multiple ways to go about proving the above question. The simplest:
a | b a b b | a b a
Step 2
Considering the fact that a,b are both positive it follows that a = b.

How to prove this inequality with the simplest means?
x 2 + 5 y 2 + 6 z 2 4 5 x y z 2 ,    if    x y > 0
I was trying to prove it. The right hand side should be nonnegative, so I can square it on both sides. But once I have done it I get to a point, where I do not see how to show, that the statement is greater or equal to 0.
x 4 + 25 y 4 + 36 z 4 + 10 x 2 y 2 + 12 x 2 z 2 + 60 y 2 z 2 80 x y z 2 0..
