    Salut!


    Tu dois transformer la forme logarithmique en forme exponentielle :

    $$log_{x} 64=6$$

    $$64=x^6$$


    Tu peux ensuite effectuer une racine sixième de chaque côté :

    $$\sqrt[6]{64}=\sqrt[6]{x^6}$$

    $$x=\sqrt[6]{64}$$


    Si tu as d'autres questions, on est là! :)
