Question

How do you integrate `(5x^4(x^6+4)^9 dx`?

Answer 1

Substitution won't simplify this problem.

You could try parts, but in the end you'll have to multiply it out and integrate term by term.

(Unless there's a typo and you meant to type:

`int 5x^4(x^5+4)^9 dx`. In which case, let `u=(x^5+4)` and integrate `u^9 du`.)
