[tex]\dfrac{\sqrt[3]{0,027}+\sqrt[3]{\frac{1}{125}}}{\sqrt[3]{0,027}-\sqrt[3]{\frac{1}{125}}}=\dfrac{\sqrt[3]{\frac{27}{1000}}+\frac{\sqrt[3]{1}}{\sqrt[3]{125}}}{\sqrt[3]{\frac{27}{1000}}-\frac{\sqrt[3]{1}}{\sqrt[3]{125}}}=\dfrac{\frac{\sqrt[3]{27}}{\sqrt[3]{1000}}+\frac{1}{5}}{\frac{\sqrt[3]{27}}{\sqrt[3]{1000}}-\frac{1}{5}}=\dfrac{\frac{3}{10}+\frac{1}{5} }{\frac{3}{10}-\frac{1}{5}}=\dfrac{\frac{3}{10}+\frac{2}{10}}{\frac{3}{10}-\frac{2}{10}}=\dfrac{\frac{5}{10}}{\frac{1}{10}}=[/tex]
