Dengan. Menggunakan integral subsitusi , tentuka setiap integral berikut a. Integral (2x - 1)5 dx b. Integr (x + 2)-10 dx

A) integral (2x - 1)^5 dx
misal u = 2x - 1
du/dx = 2
dx = du/2
integral u^5 du/2
= 1/2 u^6/6 + C
= 1/12 u^6 + C
= (2x - 1)^6 / 12 + c
B) integral (x +2)^-10 dx
misal u = x + 2
du/dx = 1
dx = du
integral u^-10 du
= u^-9 /-9 + c
= -1/9 u^-9 + C
= -1/9 (x+2)^-9 + c
