Answer 1

$\frac{a + b}{c} + \frac{b + c}{a} + \frac{c + a}{b} \geqslant 6 \\ \\ \frac{c(a + b) + a(b + c) + b(c + a)}{abc} \geqslant 6 \\ \frac{ac + bc + ab + ac + bc + ab}{abc} \geqslant 6 \\ \frac{2ab + 2bc + 2ac}{abc} \geqslant 6 \\ \frac{2(ab + bc + ac)}{abc} \geqslant 6$

Mai departe nu știu sa rezolv, insa sper ca te ajuta ceea ce am scris.
