Best ResponseYou've already chosen the best response.1\[\sf \int \frac{2x^2}{\sqrt{5+x^3}}dx\implies 2\int \frac{x^2}{\sqrt{5+x^3}}dx \]\[\sf u=5+x^3 ~,~ du = 3x^2dx \implies \frac{du}{3}=x^2dx \]resub. \[\sf \frac{2}{3}\int \frac{du}{u^{1/2}}\]

Best ResponseYou've already chosen the best response.1\[\sf 2\int\frac{1}{u^{1/2}} \cdot \frac{du}{3}= \frac{2}{3}\int\frac{du}{u^{1/2}}\]Oh okay
