Ответ:
[tex]14\frac{1}{3}[/tex]
Пошаговое объяснение:
[tex]\int\limits^5_1 {\frac{x^2dx}{5} } \,+\int\limits^6_5 {\frac{x^2dx}{5} } \,=\int\limits^6_1 {\frac{x^2dx}{5} } \,=\frac{1}{5}\int\limits^6_1 {\frac{x^2dx}{5} } \, =\frac{1}{5}*(\frac{x^3}{3}|_1^6)=\frac{1}{5}*(\frac{6^3}{3}-\frac{1^3}{3})=\\\\=\frac{1}{5}(\frac{216}{3}-\frac{1}{3})=\frac{1}{5}*\frac{215}{3}=\frac{43}{3}=14\frac{1}{3}[/tex]
