[{"id":45076,"question":"Quelle est la formule de la dérivée de la fonction f(x) = x² ?","option_a":"A. f'(x) = 2x","option_b":"B. f'(x) = x","option_c":"C. f'(x) = 2","option_d":"D. f'(x) = x²","option_e":"","option_f":"","bonne_reponse":"A","explication":"La dérivée de x² est 2x, car la règle de dérivation de x^n est n*x^(n-1). Ici, n=2, donc f'(x) = 2x.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":45077,"question":"En électricité, la loi d'Ohm s'écrit U = R * I.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"La loi d'Ohm est bien U = R * I, où U est la tension, R la résistance et I l'intensité du courant.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":45078,"question":"Quel est le résultat de l'intégrale ∫(3x² + 2x + 1) dx ?","option_a":"A. x³ + x² + x + C","option_b":"B. 6x + 2 + C","option_c":"C. x³ + x² + C","option_d":"D. 3x³ + x² + x + C","option_e":"","option_f":"","bonne_reponse":"A","explication":"L'intégrale de 3x² est x³, celle de 2x est x², et celle de 1 est x. On ajoute la constante d'intégration C.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":45079,"question":"En chimie, la formule de l'eau est H₂O.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"La formule chimique de l'eau est bien H₂O, composée de deux atomes d'hydrogène et un atome d'oxygène.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":45080,"question":"Quelle est la capitale de la Tunisie ?","option_a":"A.
