A. $\int\limits_{0}^{2}{{{x}^{3}}dx}=\left. \dfrac{{{x}^{4}}}{4} \right|_{0}^{2}$.
B. $\int\limits_{0}^{2}{{{x}^{3}}dx}=\left. 4{{x}^{4}} \right|_{0}^{2}$.
C. $\int\limits_{0}^{2}{{{x}^{3}}dx}=\left. 3{{x}^{2}} \right|_{0}^{2}$.
D. $\int\limits_{0}^{2}{{{x}^{3}}dx}=\left. \dfrac{{{x}^{2}}}{3} \right|_{0}^{2}$.
Ta có: $\int\limits_{0}^{2}{{{x}^{3}}dx}=\left. \dfrac{{{x}^{4}}}{4} \right|_{0}^{2}=4$.
