Applicare la formula: $x^a\geq b$$=\left(x^a\right)^{\frac{1}{a}}\geq b^{\frac{1}{a}}$, dove $a=2$, $b=25$ e $x=x+2$

Applicare la formula: $a^b$$=a^b$, dove $a=25$, $b=\frac{1}{2}$ e $a^b=\sqrt{25}$

Applicare la formula: $\left(x^a\right)^b$$=x$, dove $a=2$, $b=1$, $x^a^b=\sqrt{\left(x+2\right)^2}$, $x=x+2$ e $x^a=\left(x+2\right)^2$

Applicare la formula: $x+a\geq b$$=x\geq b-a$, dove $a=2$ e $b=5$

Applicare la formula: $a+b$$=a+b$, dove $a=5$, $b=-2$ e $a+b=5-2$
