\begin{align}
\begin{align}
\int x^3(2+x^4)^5dx &= \int (x^3dx)(2+x^4) = \int \left(\frac{1}{4}du\right)(u) = \frac{1}{4}\int u\,du \\[2ex]


&= \frac{1}{4} \left[\frac{u^{1+1}}{1+1}\right] + C = \frac{u^2}{8} + C \\[2ex]
\int \frac{\sin{(\ln{(x))}}}{x}dx = \int\frac{1}{x}\sin(\ln{(x)})dx
 
&= \frac{(2+x^4)^2}{8} + C
