How do you integrate x(ln3)(x2+4)? Calculus Techniques of Integration Integration by Parts 1 Answer Antoine May 2, 2015 ∫x(ln3)(x2+4)dx ln3 is a constant so this turns down to, ⇒1ln3∫xx2+4dx=1ln3∫12⋅2xx2+4dx=12ln3∫2xx2+4dx The numerator is the derivative of the denominator so, ⇒12ln3ln∣∣x2+4∣∣+C Answer link Related questions How do I find the integral ∫(x⋅ln(x))dx ?
