Question

Pls answer fast !! ​

Answer 1

Answer:

1/(1+x^(a-b))+ 1/(1+x^(b-a))

= 1/(1+x^(a-b)) + 1/(1+x^-(a-b))

=1/(1+x^(a-b)) + (x^(a-b))/(1+x^(a-b))

=(1+x^(a-b))/(1+x^(a-b))

=1

Answer 2

Sol:- let 1/1+x^a-b + 1/1+x^b-a

1/1+x^a-b + 1/1+x^-(a-b)

1/1+x^a/x^b + 1/1 x^b/x^a

x^b + x^a/ x^a + x^b=1
