$$\sqrt[n]{a}=b\leftrightarrow a=b^{n}$$

$$\sqrt[n]{a}= a^{\frac{1}{n}}$$

$$\sqrt[m]{\sqrt[n]{a}} = \sqrt[mn]{a}$$

$$\sqrt[n]{ab} = \sqrt[n]{a} \cdot \sqrt[n]{b}$$

$$\sqrt[n]{\frac{a}{b}} = \frac{\sqrt[n]{a}}{\sqrt[n]{b}}$$

$$\sqrt[m]{\frac{a^x}{b^y}} = \frac{\sqrt[m]{a^x}}{\sqrt[m]{b^x}}$$

$$\sqrt[n]{a^n} = a$$ si n es impar

$$\sqrt[n]{a^n} = \mid a \mid$$ si n es par
