Applicare la formula: $\left(ab\right)^n$$=a^nb^n$

Applicare la formula: $a^b$$=a^b$, dove $a=196$, $b=\frac{1}{2}$ e $a^b=\sqrt{196}$

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

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

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