Answer 1

$\sf\underbrace{\red{CONCEPT:-}}$

$\checkmark\:\bf\underline{\purple{\boxed{{\dfrac{a^m}{a^n}}\:=\:a^{m-n}\:}}}$

$\sf\underbrace{\red{SOLUTION:-}}$

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