\frac{1}{1+x^{(a-b)}}+\frac{1}{1+x^{(b-a)}}=1\\\implies Take\: L.H.S\colon \\\\\implies \frac{1}{1+\frac{x^{a}}{x^{b}}}+\frac{1}{1+\frac{x^{b}}{x^{a}}}

\\\implies \frac{1}{\frac{x^{b}+x^{a}}{x^{b}}}+\frac{1}{\frac{x^{a}+x^{b}}{x^{a}}}\\\implies \frac{x^{b}}{x^{b}+x^{a}}+\frac{x^{a}}{x^{a}+x^{b}}\\\implies \frac{\cancel{(x^{a}+x^{b})}}{\cancel{(x^{a}+x^{b})}}\\\implies 1

Hello!

\bf{(R.H.S.)}

\dfrac{1}{1+x^{a-b}} + \dfrac{1}{1+x^{b-a}}

= \dfrac{1}{1+\dfrac{x^{a}}{x^{b}}} + \dfrac{1}{1+\dfrac{x^{b}}{x^{a}}}

= \dfrac{x^{b}}{x^{a} + x^{b}} + \dfrac{x^{a}}{x^{a} + x^{b}}

= \dfrac{\cancel{(x^{a}+x^{b})}}{\cancel{(x^{a}+x^{b})}} = 1

\bf{(L.H.S.)}

\boxed{\red{\bf{HENCE\:PROVED}}}

Cheers!
