Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}\frac{radicalfactor\left(b\right)}{radicalfactor\left(b\right)}$, dove $a=4$ e $b=\sqrt{4-16x^2-8x}$

Applicare la formula: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, dove $a=4$, $b=\sqrt{4-16x^2-8x}$, $c=\sqrt{4-16x^2-8x}$, $a/b=\frac{4}{\sqrt{4-16x^2-8x}}$, $f=\sqrt{4-16x^2-8x}$, $c/f=\frac{\sqrt{4-16x^2-8x}}{\sqrt{4-16x^2-8x}}$ e $a/bc/f=\frac{4}{\sqrt{4-16x^2-8x}}\frac{\sqrt{4-16x^2-8x}}{\sqrt{4-16x^2-8x}}$

Applicare la formula: $x\cdot x$$=x^2$, dove $x=\sqrt{4-16x^2-8x}$

Applicare la formula: $\left(x^a\right)^b$$=x$, dove $a=\frac{1}{2}$, $b=2$, $x^a^b=\left(\sqrt{4-16x^2-8x}\right)^2$, $x=4-16x^2-8x$ e $x^a=\sqrt{4-16x^2-8x}$
