# Thread: Integration By Parts Confirmation

1. ## Integration By Parts Confirmation

Is ∫ $(x*(ln(x)^4) = 4ln|x|^3-12ln|x|$

2. just check it yourself,
derive the right side,and see if you get the left side.
cant go safer than that

No.

$\int x \ln{(x)^4} ~ dx = 4 \int x\ln{x}~dx = 2 \int (x^2)'\ln{x}~dx$

Now apply integration by parts.
