If `int(5x^(4)+4x^(5))/((x^(5)+x+1)^(2))dx=f(x)+C`, then the value of `(1)/(f(1))` is

If f(x)=int((5x^4+4x^5))/((x^5+x+1)^(2))dx and f(0)=0, then the value of f(1) is :

int(x^(3)-4x^(2)+5x-1)/((x-1)^(2))dx

int(1)/(x^(4)+5x^(2)+1)dx

int_(0)^(1)(x^(6)-4x^(5)+5x^(4)-4x^(2))dx

If f(x) = int(5x^(8)+7x^(6))/((x^(2)+1+2x^(7))^(2))dx, (x ge 0) , and f(0) = 0, then the value of f(1) is

Let f(x)=x^(5)+2x^(3)+3x+4 then the value of 28(d)/(dx)(f^(-1)) at x=-2 is

If m is a non-zero number and int(x^(5m-1)+2x^(4m-1))/((x^(2m)+x^(m)+1)^(3))dx=f(x)+c, then f(x) is:

"int_(-1)^(4)(x^(5)+2x^(2)+x)dx

int(1)/((x+1)[(x+1)^(4)+1])dx=(1)/(4)*log f(x)+c then the value of f(x) at x=1 is
