Ta có \(\int _{0}^{10}f\left(x\right)dx =\int _{0}^{2}f\left(x\right)dx +\int _{2}^{4}f\left(x\right)dx +\int _{4}^{10}f\left(x\right)dx \)
\({\Rightarrow \int _{0}^{2}f\left(x\right)dx +\int _{4}^{10}f\left(x\right)dx =\int _{0}^{10}f\left(x\right)dx -\int _{2}^{4}f\left(x\right)dx } \\ {\, \, \, \, \, =7-3=4.} \)
