Simplify $\sqrt{y^3}$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $3$ and $n$ equals $\frac{1}{2}$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=2$, $c=3$, $a/b=\frac{1}{2}$ e $ca/b=3\cdot \left(\frac{1}{2}\right)$

Moltiplicare il termine singolo $2$ per ciascun termine del polinomio $\left(y-\sqrt{y^{3}}\right)$
