Dear Student,
Int of (x-x^5)^1/5/x^6 dx
= Int of [(x^5)^1/5 . (1/x^4 – 1)^1/5]/x^6 dx
= Int of (1/x^4-1)^1÷5 / x^5 dx
Suppose, 1/x^4 – 1= z
So,dz = -4/x^5 dx
So, 1/x^5 dx = - ¼ dz
Putting the values we get,
-1/4 Int of z^1/5 dz
= -1/4 x. 5/6 . z^6/5 + c
= - 5/24 ( 1/x^4-1)^6/5 + c ( putting the values) .
Cheers!!
