f(x)=(√(3+x^3 ))  f(1)=2   m=2  f(3)=(√(30))  M=(√(30))   ∫_1 ^3 (√(30)) dx>∫_1 ^3 (√(3+x^3 )) dx>2∫_1 ^3 dx  2(√(30)) >∫_1 ^3 (√(3+x^3 )) dx>2(2)  2(√(30)) >∫_1 ^3 (√(3+x^3 )) dx>4

$${f}\left({x}\right)=\sqrt{\mathrm{3}+{x}^{\mathrm{3}} }\:\:{f}\left(\mathrm{1}\right)=\mathrm{2}\:\:\:{m}=\mathrm{2} \\ $$$${f}\left(\mathrm{3}\right)=\sqrt{\mathrm{30}}\:\:{M}=\sqrt{\mathrm{30}}\: \\ $$$$\int_{\mathrm{1}} ^{\mathrm{3}} \sqrt{\mathrm{30}}\:{dx}>\int_{\mathrm{1}} ^{\mathrm{3}} \sqrt{\mathrm{3}+{x}^{\mathrm{3}} }\:{dx}>\mathrm{2}\int_{\mathrm{1}} ^{\mathrm{3}} {dx} \\ $$$$\mathrm{2}\sqrt{\mathrm{30}}\:>\int_{\mathrm{1}} ^{\mathrm{3}} \sqrt{\mathrm{3}+{x}^{\mathrm{3}} }\:{dx}>\mathrm{2}\left(\mathrm{2}\right) \\ $$$$\mathrm{2}\sqrt{\mathrm{30}}\:>\int_{\mathrm{1}} ^{\mathrm{3}} \sqrt{\mathrm{3}+{x}^{\mathrm{3}} }\:{dx}>\mathrm{4} \\ $$$$ \\ $$
