Applicare la formula: $x,\:a,\:b$$=eval\left(x,a,b\right)$, dove $a=a=0.5$, $b=b=-0.4$, $x=5a^2-3b$ e $x;a=5a^2-3b,\:a=0.5,\:b=-0.4$

Applicare la formula: $ab$$=ab$, dove $ab=-3\cdot -0.4$, $a=-3$ e $b=-\frac{2}{5}$

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

Applicare la formula: $ab$$=ab$, dove $ab=5\cdot 0.25$, $a=5$ e $b=\frac{1}{4}$

Applicare la formula: $a+b$$=a+b$, dove $a=\frac{5}{4}$, $b=\frac{6}{5}$ e $a+b=1.25+1.2$
