Aplicamos a regra: $\frac{d}{dx}\left(x^a\right)$$=ax^{\left(a-1\right)}$, onde $a=\frac{3}{4}$

Aplicamos a regra: $x^a$$=\frac{1}{x^{\left|a\right|}}$

Aplicamos a regra: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, onde $a=3$, $b=4$, $c=1$, $a/b=\frac{3}{4}$, $f=x^{\left|-\frac{1}{4}\right|}$, $c/f=\frac{1}{x^{\left|-\frac{1}{4}\right|}}$ e $a/bc/f=\frac{3}{4}\frac{1}{x^{\left|-\frac{1}{4}\right|}}$

Aplicamos a regra: $\frac{a}{b}\frac{c}{f}$$=\frac{ac}{bf}$, onde $a=3$, $b=4$, $c=1$, $a/b=\frac{3}{4}$, $f=\sqrt[4]{x}$, $c/f=\frac{1}{\sqrt[4]{x}}$ e $a/bc/f=\frac{3}{4}\frac{1}{\sqrt[4]{x}}$
