If`y=1/(1+x^(a-b)+x^(c-b))+1/(1+x^(b-c)+x^(a-c))+1/(1+x^(b-a)+x^(c-a)),`then (dy)/(dx) is equal to(a)`1`(b) `(a+b+c)^(x+b+c-1)``0`(d) none of these

If`y=1/(1+x^(a-b)+x^(c-b))+1/(1+x^(b-c)+x^(a-c))+1/(1+x^(b-a)+x^(c-a))

1.	If`y=1/(1+x^(a-b)+x^(c-b))+1/(1+x^(b-c)+x^(a-c))+1/(1+x^(b-a)+x^(c-a)),`then (dy)/(dx) is equal to(a)`1`(b) `(a+b+c)^(x+b+c-1)``0`(d) none of these
Answer» `y = 1/(1 + x^a/x^b + x^c/x^b) + 1/(1 + x^b/x^c + x^a/x^c) + 1/(1+x^b/x^a + x^c/x^a)` `y = x^b/(x^a + x^b + x6c) + x^c/(x^a + x^b + x^c) + x^a/(x^a + x^b + x^c) ` `= (x^b + x^c + x^a )/(x^a + x^b + x^c) = 1` `y = 1` `dy/dx = 0` option c is correct
