Applicare la formula: $x,\:a,\:b$$=eval\left(x,a,b\right)$, dove $a=b=-0.5$, $b=y=\frac{2}{3}$, $x=3b^2c+2b$ e $x;a=3b^2c+2b,\:b=-0.5,\:y=\frac{2}{3}$

Applicare la formula: $ab$$=ab$, dove $ab=2\cdot -0.5$, $a=2$ e $b=-\frac{1}{2}$

Applicare la formula: $a^b$$=a^b$, dove $a=-\frac{1}{2}$, $b=2$ e $a^b={\left(-0.5\right)}^2$

Applicare la formula: $ab$$=ab$, dove $ab=3\cdot 0.25c$, $a=3$ e $b=\frac{1}{4}$
