Applicare la formula: $x,\:a,\:b$$=eval\left(x,a,b\right)$, dove $a=b=2$, $b=m=\frac{1}{2}$, $x=b^2mn$ e $x;a=b^2mn,\:b=2,\:m=\frac{1}{2}$

Applicare la formula: $a^b$$=a^b$, dove $a=2$, $b=2$ e $a^b=2^2$

Applicare la formula: $\frac{a}{b}c$$=\frac{ca}{b}$, dove $a=1$, $b=2$, $c=4$, $a/b=\frac{1}{2}$ e $ca/b=4\cdot \left(\frac{1}{2}\right)n$

Applicare la formula: $ab$$=ab$, dove $ab=4\cdot 1$, $a=4$ e $b=1$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=4$, $b=2$ e $a/b=\frac{4}{2}$
