int e^(x^(4))(x+x^(3)+2x^(5))e^(x^(2))*dx is equal to a.(1)/(2)xe^(x^(2))e^(x^(4))+c b.(1)/(2)x^(2)e^(x^(4))+c c.(1)/(2)e^(x^(2))e^(x^(4))+cd(1)/(2)x^(2)e^(x^(2))e^(x^(4))+c

int(e^(x))/(x^(4))dx=-(e^(x))/(3)[(1)/(x^(3))+(1)/(2x^(2))+(1)/(2x)]+(1)/(6)int(e^(x))/(x)dx

Prove that, int (e^(x))/(x^(4))dx=-(e^(x))/(3)[(1)/(x^(3))+(1)/(2x^(2))+(1)/(2x)]+(1)/(6)int (e^(x))/(x)dx .

int e^(x^(4))(x+x^(3)+2x^(5))e^(x^(2))dx is equal to (1)/(2)xe^(x^(2))e^(x^(4))+c( b) (1)/(2)x^(2)e^(x^(4))+c(1)/(2)e^(x^(2))e^(x^(4))+c(d)(1)/(2)x^(2)e^(x^(2))e^(x^(4))+c

(d)/(dx)[log{e^(x)((x-2)/(x+2))^(3/4)}] equals (x^(2)-1)/(x^(2)-4) (b) 1 (c) (x^(2)+1)/(x^(2)-4) (d) e^(x)(x^(2)-1)/(x^(2)-4)

int e^(x)((x^(4)+x^(2)+1)/(x^(2)+x+1))dx=
