Question

please help me
how to integrate x^2d(x^2)..? and x^3d(x^2)...

Answer 1

in first one,,let x^2=t and you are left with integral t dt..
in second one,,,let x^2 =t,,so x^3 = t^3/2 //so you need to integrate t^3/2 dt..
should be easier then..

Answer 2

I have done earlier as you told but mine answer was not matched, then I post the problem, there might be answer -mistake in book.

Answer 3

(x^4)/2
and (x^5) * 2/5
you sure these dont match ?
