Explicacipaso:

$\sqrt[3]{2^{-3}}=\sqrt[3]{\frac{1}{2^{3}}}=\frac{\sqrt[3]{1}}{\sqrt[3]{2^{3}}}=\frac{\sqrt[3]{1}}{\sqrt[3]{8}}=\\\\=\frac{1}{2}$

$\left(\frac{2}{5}\right)^{-2}=\frac{1}{\left(\frac{2}{5}\right)^{2}}=\frac{1}{\frac{4}{25}}=\\\\=\frac{25}{4}\\\\\left(\frac{3}{8}\right)^{-1}=\frac{1}{\left(\frac{3}{8}\right)^{1}}=\frac{8}{3}\\\sqrt[3]{2^{-3}}+\frac{13}{4}+\left(\frac{2}{5}\right)^{-2}+\left(\frac{3}{8}\right)^{-1}\div4=\frac{\frac{1}{2}+\frac{13}{4}+\frac{25}{4}+\frac{8}{3}}{4}=\frac{19}{6}$
