Applicare la formula: $ab$$=ab$, dove $ab=7\cdot -32$, $a=7$ e $b=-32$

Applicare la formula: $a^n$$=\left(-a\right)^ni$, dove $a^n=\sqrt{-224}$, $a=-224$ e $n=\frac{1}{2}$

Applicare la formula: $\left(ab\right)^n$$=a^nb^n$, dove $a=\sqrt{224}$, $b=i$ e $n=\frac{1}{2}$

Applicare la formula: $\left(x^a\right)^b$$=x^{ab}$, dove $a=\frac{1}{2}$, $b=\frac{1}{2}$, $x^a^b=\sqrt{\sqrt{224}}$, $x=224$ e $x^a=\sqrt{224}$

Applicare la formula: $x\cdot x$$=x^2$, dove $x=\frac{1}{2}$
