Applicare la formula: $\int_{a}^{b} cxdx$$=c\int_{a}^{b} xdx$, dove $a=1$, $b=3$, $c=x^2$ e $x=\sqrt{y}$

Applicare la formula: $\int x^ndx$$=\frac{x^{\left(n+1\right)}}{n+1}+C$, dove $x=y$ e $n=\frac{1}{2}$

Applicare la formula: $\frac{a}{\frac{b}{c}}$$=\frac{ac}{b}$, dove $a=\sqrt{y^{3}}$, $b=3$, $c=2$, $a/b/c=\frac{\sqrt{y^{3}}}{\frac{3}{2}}$ e $b/c=\frac{3}{2}$

Applicare la formula: $\left[x\right]_{a}^{b}$$=eval\left(x,b\right)-eval\left(x,a\right)+C$, dove $a=1$, $b=3$ e $x=\frac{2\sqrt{y^{3}}}{3}$
