Pour calculer √(2) × 2√(2), suivez ces étapes : Step 1: Réécrivez l'expression pour regrouper les termes. √(2) × 2√(2) = 2 × √(2) × √(2); Step 2: Multipliez les racines carrées. Rappelez-vous que √(a) × √(a) = a. 2 × √(2) × √(2) = 2 × 2 Step 3: Effectuez la multiplication finale. 2 × 2 = 4 Le résultat est : 4
