$\int_{0}^{1} \frac{1}{1+\sqrt[3]{x} } dx$ $u=\sqrt[3]{x}$ $du=\frac 1 3 \frac{1}{\sqrt[3]{x^2}}dx$ $3du=\frac{1}{\sqrt[3]{x^2}}dx$ $3\sqrt[3]{x^2}du=dx$ $3u^2du=dx \*\possible\error$ $\int_{0}^{1} \frac{3u^2}{1+u } du$ $3\int_{0}^{1} \frac{u^2}{1+u } du$ long division $u-1+\frac{1}{u+1}$ $3\int_{0}^{1} udu-3\int_{0}^{1} 1du+3\int_{0}^{1} \frac{1}{u+1}du$ something is missing...
