If`int1/(x+x^5)dx=f(x)+c ,t h e ne v a l u a t eint(x^4)/(x+x^5)dxdot`

1.	If`int1/(x+x^5)dx=f(x)+c ,t h e ne v a l u a t eint(x^4)/(x+x^5)dxdot`A. `logx-f(x)+C`B. `f(x)+logx+C`C. `f(x)-logx+C`D. None of these
Answer» Correct Answer - A Let`" "l=int(x^(4))/(x+x^(5))dx=int(x^(4)+1-1)/(x+x^(5))dx` `rArr" "l=int(1)/(x)dx-int(1)/(x^(5)+x)dx` `rArr" "l=logx-[f(x)+C]" [Given]"` `rArr" "l=logx-f(x)+C_(1)" "["where, "C_(1)=-C]`
