Tích phân $\Large \int\limits_1^2e^{3x-1}\mathrm{d}x$ bằng

• A.

  $\Large \dfrac{1}{3}(e^5-e^2).$

• B.

  $\Large \dfrac{1}{3}(e^5+e^2).$

• C.

  $\Large \dfrac{1}{3}e^5-e^2.$

• D.

  $\Large e^5-e^2.$

Chọn A

$\Large \int\limits_1^2e^{3x-1}\mathrm{d}x=\left(\dfrac{1}{3}e^{3x-1}\right)\bigg|_1^2=\dfrac{1}{3}(e^5-e^2).$
