`int dx/(x(x^6+1))`

Evaluate: int(dx)/(x^2(x^6+1)^(5/6))

If int dx/(x^6 + x^4) = tan^-1x + 1/x + k/x^3 + c , then value of k is

int(dx)/(x(1+4x^(3)+3x^(6)))

int (x^(6) -(1)/(x) +e^(x) +3)dx

int (5(x^(6)+1))/(x^(2)+1)dx=....

The value of int(dx)/(x^(13)(x^(6)-1)) is

Evaluate int(dx)/(x sqrt(x^(6)-1))

"If"int(dx)/(x^(3)(1+x^(6))^(2/3))=xf(x)(1+x^(6))^(1/3)+C where, C is a constant of integration, then the function f(x) is equal to

If int(dx)/(x^(3)(1+x^(6))^(2/3))=xf(x)(1+x^(6))^(1/3)+C where, C is a constant of integration, then the function f(x) is equal to
