Answer 1

$= \ \textgreater \ \frac{1}{1 + x^{b-a} + x^{c-a} } + \frac{1}{1 + x^{a-b} + x^{c-b} } + \frac{1}{1 + x^{b-c} + x^{a-c} }$

$= \ \textgreater \ \frac{1}{1 + \frac{x^b}{x^a} + \frac{x^c}{x^a}} + \frac{1}{1 + \frac{x^a}{x^b} + \frac{x^c}{x^b} } + \frac{1}{ \frac{x^b}{x^c} + \frac{x^a}{x^c} }$

$= \ \textgreater \ \frac{x^a}{x^a + x^b +x^c} + \frac{x^b}{x^b+x^a+x^c} + \frac{x^c}{x^c+x^a+x^b}$

$= \ \textgreater \ \frac{x^a+x^b+x^c}{x^a+x^b+x^c}$

= > 1.


Hope this helps!
