\[\large \sqrt[3]{\frac{(a+b)(b+c)(c+a)}{abc}}\geq\frac{4}{3}\bigg(\frac{a^2}{a^2+bc}+\frac{b^2}{b^2+ac}+\frac{c^2}{c^2+ab}\bigg)\] If \(a,b\) and \(c\) are positive reals, prove the inequality above.
I've proven So now I have to prove I've tried to prove it but then realised that what I was trying to prove is wrong, can somebody help me?

How did you proved the first part

First can be proved easily using AM-GM inequality.

Yes just saw that
I proved it up to the lhs is greater than or equal to 427abc/( (a+b+c)^3+27abc)
