Solution steps

Apply radical rule:

= (2 0^{\frac{1}{4}})^{\frac{1}{3}}

Apply exponent rule:

(a^{b})^{c} = a^{b c}

= 2 0^{\frac{1}{4} \cdot \frac{1}{3}}

\frac{1}{4} \cdot \frac{1}{3} = \frac{1}{12}

= 2 0^{\frac{1}{12}}

x^{2} (7 x)

(- p)^{p} (- p)^{p}

(e^{- x} - x e^{- x}) \cdot e^{- x}

((- 1.5)^{3})^{3}

\frac{2 ^{\frac{1}{2}}}{5 ^{\frac{1}{2}}}
