\sqrt[n]{a}

Definition

$a$ to the power $1 / n$ , +

$n$ ^th^ root of $a$

$a$ puissance $1 / n$ , + racine $n$ ^ième^ de $a$

Notes

If $a \geq 0$ , then $\sqrt[n]{a} \geq 0$ .

The symbol without the upper line $\sqrt[n]{a}$ should be avoided.

If however the symbol $\sqrt[n]{}$ or $\sqrt{}$ is used acting on a composite expression, parentheses shall be used to avoid ambiguity.

Si $a \geq 0$ , alors $\sqrt[n]{a} \geq 0$ .

Il convient d'éviter le symbole sans la ligne supérieure $\sqrt[n]{a}$ .

Toutefois, si le symbole $\sqrt[n]{}$ ou $\sqrt{}$ est utilisé pour agir sur une expression composée, des parenthèses doivent être utilisées pour éviter toute ambiguïté.
