If `f(x)=(3^(1+ln x)/(x^(ln3)))` then `f(1993)` is

If f (x) = ln _(x) (ln x ), then f'(e) =

If f.(x)= log((1+x)/(1-x)) , then

If f.(x)= log((1+x)/(1-x)) , then

If f(x)=log((1+x)/(1-x)) and g(x)=((3x+x^(3))/(1+3x^(2))) then f(g(x)) is equal to f(3x)(b)quad {f(x)}^(3) (c) 3f(x)(d)-f(x)

If f(x)=log ((1+x)/(1-x)) , then

If f(x)=log((1+x)/(1-x)),-1ltxlt1 then f((3x+x^(3))/(1+3x^(2)))-f((2x)/(1+x^(2))) is

if f(x)=x^(3)ln(x) then d(f(x))/(dx)=

If f(x)=log((1+x)/(1-x))a n dg(x)=((3x+x^3)/(1+3x^2)) , then f(g(x)) is equal to (a) f(3x) (b) {f(x)}^3 (c) 3f(x) (d) -f(x)

If f(x)=tan^(-1)[(log((e )/(x^(2))))/(log (ex^(2)))]+tan^(-1)[(3+2 log x)/(1-6 log x)] then the value of f''(x) is
