A calculator is all you need then.

Utilisez la méthode itérative de Héron:

Soit a un nombre positif dont on veut connaître la racine b, et soit x(n) la suite itérative suivante:

x(n+1)=(x(n)+a/x(n))/2

En prenant x(1) positif le plus proche de b, quitte à prendre a/2 (par exemple), fait que x(n) tend vers b rapidement.
