∫X (X + 3) PANGKAT 4 DX ADALAH =

int x(x + 3)⁴ dx = int u'dv

int u'dv = uv - int v du

int x(x+3)⁴ dx

u = x ----------- dv = (x + 3)⁴ dx
du = dx -------- v = 1/5 (x + 3)⁵

int u'dv = uv - int v du

= x. (1/5 (x + 3)⁵) - int 1/5 (x + 3)⁵ dx
= x/5 (x + 3)⁵ - 1/30 (x + 3)⁶
= 1/5 ( x(x + 3)⁵ - 1/6 (x + 3)⁶)
