Chọn các khẳng định đúng
Nếu  f,gf,g  là hai hàm số liên tục trên  KK  thì

 [f(x)+g(x)]dx=f(x)dx+g(x)dx\int_{ }\left[f\left(x\right)+g\left(x\right)\right]dx=\int f\left(x\right)dx+\int g\left(x\right)dx  

 kf(x)dx=kf(x)dx\int kf\left(x\right)dx=k\int f\left(x\right)dx  

 [f(x).g(x)]dx=f(x)dx.g(x)dx\int_{ }\left[f\left(x\right).g\left(x\right)\right]dx=\int f\left(x\right)dx.\int g\left(x\right)dx
