Are you thinking of this way that since x,y,z > 0,
So we can consider that they are sides of a triangle and that
the sum of two sides is greater than the third side?
and then do the remaining?
or we can use this as well (x + y + z)(1/x + 1/y + 1/z)  9
I can't think of any shorter way!

All that is gold does not glitter
Not all who wander are lost
The old that is strong does not wither,
Deep roots are not reached by frost.
From ashes a fire shall be woken
From shadows a light shall spring
Renewed shall be blade that's broken
The crown less again shall be king. |
