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

Show that: (1)/(1+x^(a-b))+(1)/(1+x^(b-a))=1

Solve: 1/(1+x^(a-b))+1/(1+x^(b-a))=?

Prove that: (1)/(1+x^(a-b))+(1)/(1+x^(b-a))=1

Prove that: 1/(1+x^(a-b))+1/(1+x^(b-a))=1

Find the value of (1)/(1+x^(a-b))+(1)/(1+x^(b-a))

Prove that (i) (a^(-1))/(a^(-1) + b^(-1)) + (a^(-1))/(a^(-1)-b^(-1)) = (2b^(2))/(b^(2) -a^(2)) (ii) (1)/(1+x^(a-b)) + (1)/(1+x^(b-a)) = 1

Show that: (i) (x^(a(b-c)))/(x^(b(a-c)))-:((x^b)/(x^a))^c=1,

Show that: (i)\ (x^(a-b))^(a+b)\ (x^(b-c))^(b+c)\ (x^(c-a))^(c+a)=1 (ii)\ {(x^(a-a^(-1)))^(1/(a-1))}^(a/(a+1))=x
