Raisonnement par équivalence - Logique Mathématique - 1 Bac SM S.ex - [Exercice 27]

In this video, I'll cover an exercise (Moufid exercise 24, page 71) "Mathematical Logic," in which we'll apply equivalence reasoning. This video is intended for first-year baccalaureate students (Science, Mathematics, and Mathematics). 💡Remember, it's important to try to work through the exercise before looking at the answer key. ▬▬▬▬▬▬▬▬▬▬▬▬ EXERCISE ▬▬▬▬▬▬▬▬▬ 1) Show that for all x∈R_+* ∶ x+1/x≥2 2) Deduce that for all (a,b,c)∈(R_+* )^3 ∶ (a+b+c)(1/a+1/b+1/c)≥9 00:29 Exercise statement 00:48 Method 1 04:03 Method 2 ▬▬▬▬▬▬▬ BRANCHES CONCERNED ▬▬▬▬▬▬▬ 1 Baccalaureate in Science 1 Baccalaureate in Sex 1 Baccalaureate in Mathematics 1 Baccalaureate in Physics 1 Baccalaureate in Life Sciences 1 Baccalaureate in Experimental Sciences ▬▬▬▬▬▬▬ SUBSCRIBE ▬▬▬▬▬▬▬ 💡👉 Subscribe here:    / @mathphys   ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 🔔 Thank you Click the LIKE button if you enjoy our content and subscribe to our YouTube channel to receive our new videos. 👉Let me know your questions in the comments section if you don't understand something! 😀 💡Please also remember to SHARE with your friends!!💪💪🔥🔥 ▬▬▬▬▬▬▬ SOCIAL MEDIA ▬▬▬▬▬▬▬   / 536279063660093     / math-phys-112225370317476     / math.phys     / mathphys5   ▬▬▬▬▬▬▬ SIMILAR VIDEOS ▬▬▬▬▬▬▬ Reasoning by Equivalence - Mathematical Logic - 1st Baccalaureate (Science and Mathematics) - [Exercise 27]:    • Raisonnement par équivalence - Logique Mat...   Reasoning by Equivalence - Mathematical Logic 1st Baccalaureate (Science and Mathematics) - [Exercise 11]:    • Raisonnement par équivalence - Logique Mat...   Reasoning by Disjunction of Cases - Mathematical Logic - 1st Baccalaureate (Science and Mathematics) - [Exercise 26]:    • Raisonnement par Disjonction des Cas - Log...   Reasoning by Disjunction of Cases - Mathematical Logic 1st Baccalaureate (Science and Mathematics) - [Exercise 10]:    • Raisonnement par Disjonction des Cas - Log...   Reasoning by Implication - Mathematical Logic - 1st Baccalaureate (Science and Mathematics) - [Exercise [25]:    • Raisonnement par Implication - Logique Mat...   Reasoning by Recurrence - Mathematical Logic 1st Baccalaureate (Sms) - Exercise 5:    • Raisonnement par Récurrence - Logique Math...   Reasoning by Counter-Example - Mathematical Logic - 1st Baccalaureate (Sms) - [Exercise 24]:    • Raisonnement par Contre Exemple - Logique ...   Truth Value of a Proposition - Mathematical Logic - 1st Baccalaureate (Sms) - [Exercise 23]:    • Valeur de Vérité d'une Proposition - Logiq...   Reasoning by Disjunction of Cases - Mathematical Logic 1st Baccalaureate (Sms) - [Exercise 10]:    • Raisonnement par Disjonction des Cas - Log...   Truth Value of a Proposition - Mathematical Logic 1st Baccalaureate (Sms) S.ex [Exercise 9]:    • Valeur de Vérité d'une Proposition - Logiq...   Reasoning by Recurrence - Mathematical Logic 1st Baccalaureate (Sms) S.ex [Exercise 8]:    • Raisonnement par Récurrence - Logique Math...   Reasoning by Adversarialism - Mathematical Logic 1st Baccalaureate (Sms) S.ex [Exercise 7]:    • Raisonnement par l'absurde - Logique Mathé...   Negation of a Proposition - Mathematical Logic - 1st Baccalaureate (Sms) [Exercise 6]:    • Négation d'une Proposition - Logique Mathe...   Reasoning by Recurrence - Mathematical Logic 1st Baccalaureate (Sms) S.ex - [Exercise 5]:    • Raisonnement par Récurrence - Logique Math...   Reasoning by Implication - Mathematical Logic 1st Baccalaureate (Sms) S.ex [Exercise 3]:    • Raisonnement par Implication - Logique Mat...   Reasoning by Absurdity - Mathematical Logic 1st Baccalaureate (Sms/S.Eng.)
