दिया गया है:

mxm  = nxn 

गणना

mxm  = nxn 

m/n = xn/xm

इसलिए, m = xn तथा n = xm

\(\frac{1}{{{x^m} + {x^n}}} + \frac{1}{{{x^m} - {x^n}}}\)

मानों को प्रतिस्थापित करने पर,

\(\frac{1}{{{n} + {m}}} + \frac{1}{{{n} - {m}}}\)

 2n/(n2 - m2)

व्यंजक को xn से गुणा करने पर,

 2n × xn/xn(n2 - m2)

अब अंश में m = xn रखने पर,

 2mn/xn(n2 - m2)

∴ विकल्प 4 सही उत्तर है।
