(ii) `(x^l/x^m)^(l+m-n)xx(x^m/x^n)^(m+n-l) xx (x^n/x^l)^(n+l-m)=1`

(x^l /x^m)^n.(x^m/x^n)^l. (x^n/x^l)^m=

If f(x)=((x^(l))/(x^(m)))^(l+m)((x^(m))/(x^(n)))^(m+n)((x^(n))/(x^(l)))^(n+l) then f'(x)

If f(x)=((x^(l))/(x^(m)))^(l+m)((x^(m))/(x^(n)))^(m+n)((x^(n))/(x^(l)))^(n+l) then f'(x) is equal to (a) 1 (b) 0 (c) x^(l+m+n) (d) none of these

((x^(m))/(x^(n)))^(m+n)*((x^(n))/(x^(l)))^(n+l)*((x^(l))/(x^(m)))^(l+m)

Simplify: ((x^(a+b))/(x^(c)))^(a-b)((x^(b+c))/(x^(a)))^(b-c)((x^(c+a))/(x^(b)))^(c-a)(x^(l))/(x^(m))lm x(x^(m))/(x^(n))mnx(x6n)/(x^(l))ln

Differential coefficient of (x^((l+m)/(m-n)))^(1/(n-l))*(x^((m+n)/(n-l)))^(1/(l-m))*(x^((n+l)/(l-m)))^(1/(m-n)) wrt x is

(log x)/(l+m-2n)=(log y)/(m+n-2l)=(log z)/(n+l-2m)

(x^(m+n)times x^(n+l)times x^(l+m))/((x^(m)times x^(n)times x^(l))^(2))=1
