1/{1+x^(b-a) + x^(c-a)} = 1st equation
1/1+x^b/x^a +x^c/x^a
LCM kr ke solve kr de na
1/(x^a+x^b+x^c)/x^a=x^a/(x^a+x^b+x^c) = second equation
similarlay 1/1+x^(a-b) +x^(c-b) = x^b/(x^a+x^b+x^c)
and again this pattern = x^c/(x^a+x^b+x^c) = third equation
add all these three equation we get
x^a/(x^a+x^b+x^c )+ x^b/(x^a+x^b+x^c) + x^c/(x^a+x^b+x^c) by taking LCM we get
(x^a+x^b+x^c)/(x^a+x^b+x^c) = 1
