Sorry, someone please delete this.. I need sleep before tackling anything else
As much help as possible would be appreciated for this difficult problem I have been stressing over for the past few days!
Prove that [(x^3 + y^3 + z^3)/3]^2 is greater than or equal to [(x^2 + y^2 + z^2)/3]^3
really need a solid proof to this questions as quickly as possible!
