a) Cho
$a, b, c
$ là cạnh của tam giác.
CM bất đẳng thức sau :
$\frac{a^{3}}{b^{2}-bc+c^{2}} + \frac{b^{3}}{c^{2}-ca+a^{2}} + \frac{c^{3}}{a^{2}-ab+b^{2}}\geq a+b+c
$
b) Cho
$a;b;c > 0 .
$
CMR :
$\frac{a^{5}}{b^{5}+c^{5}} + \frac{b^{5}}{c^{5}+c^{5}} + \frac{c^{5}}{a^{5}+b^{5}} \geq \frac{a}{b+c} + \frac{b}{c+a} + \frac{c}{a+b}
