Best ResponseYou've already chosen the best response.0\[\int\limits_{}^{}(xx^2) dx=\frac{x^{1+1}}{1+1}\frac{x^{2+1}}{2+1}+C\] \[\int\limits_{a}^{b}f(x) dx=F(x)_a^b=F(b)F(a)\]

Best ResponseYou've already chosen the best response.0\[\int\limits\limits_{}^{}(xx^2) dx=\frac{x^{1+1}}{1+1}\frac{x^{2+1}}{2+1}+C \] \[\int\limits_{2}^{2}(xx^2) dx=[\frac{x^2}{2}\frac{x^3}{3}]^2_{2}=[\frac{2^2}{2}\frac{2^3}{3}][\frac{(2)^2}{2}\frac{(2)^3}{3}]\] \[=[2\frac{8}{3}][2+\frac{8}{3}]=2\frac{8}{3}2\frac{8}{3}=22\frac{8}{3}\frac{8}{3}=0\frac{16}{3}\]
