Applicare la formula: $x+a\geq b$$=x\geq b-a$, dove $a=12$, $b=9$ e $x=s^6$

Applicare la formula: $a+b$$=a+b$, dove $a=9$, $b=-12$ e $a+b=9-12$

Applicare la formula: $x^a\geq b$$=\left(x^a\right)^{\frac{1}{a}}\geq b^{\frac{1}{a}}$, dove $a=6$, $b=-3$ e $x=s$

Applicare la formula: $a^n$$=\left(-a\right)^ni$, dove $a^n=\sqrt[6]{-3}$, $a=-3$ e $n=\frac{1}{6}$

Applicare la formula: $\left(x^a\right)^b$$=x$, dove $a=6$, $b=1$, $x^a^b=\sqrt[6]{s^6}$, $x=s$ e $x^a=s^6$
