Answer 1

$\mathfrak{\overbrace{\underbrace{\pink{\fbox{\green{\blue{\bf\:S}\pink{o}\red{l}\orange{u}\purple{t}\blue{i}\green{o}\red{n}}}}}}}$

$\purple\longmapsto\tt \: \dfrac{1}{1 + {x}^{a - b}} + \dfrac{1}{1 + {x}^{b - a}}\\ \\\purple\longmapsto\tt \: \dfrac{1}{1 + \frac{ {x}^{a} }{ {x}^{b} } } + \dfrac{1}{1 + \frac{ {x}^{b} }{ {x}^{a} } } \\ \\ \purple\longmapsto\tt \:\frac{1}{ \frac{ {x}^{b} + {x}^{a} }{ {x}^{b} } } + \frac{1}{ \frac{ {x}^{a} + {x}^{b} }{ {x}^{a} } } \\ \\ \purple\longmapsto\tt \: \frac{ {x}^{b} }{ {x}^{a} + {x}^{b}} + \frac{ {x}^{a} }{ {x}^{a} + {x}^{b}} \\ \\ \purple\longmapsto\tt \: \frac{ \cancel{{x}^{a} + {x}^{b}}}{ \cancel{{x}^{a} + {x}^{b}}} \\ \\ \purple\longmapsto\tt \: \bold{\boxed{\large{\boxed{\orange{\small{\boxed{\large{\red{\bold{1}}}}}}}}}}$
