Ecrire de la façon la plus simple pissible: C= 4 3 ------- + -------- 1- V2 1 + V2 V2 = RACINE CARRE DE 2 Svp aider moi je su

Bonjour Vivii

[tex]C=\dfrac{4}{1-\sqrt{2}}+\dfrac{3}{1+\sqrt{2}}\\\\C=\dfrac{4(1+\sqrt{2})}{(1-\sqrt{2})(1+\sqrt{2})}+\dfrac{3(1-\sqrt{2})}{(1+\sqrt{2})(1-\sqrt{2})}\\\\C=\dfrac{4(1+\sqrt{2})+3(1-\sqrt{2})}{(1+\sqrt{2})(1-\sqrt{2})}\\\\C=\dfrac{4+4\sqrt{2}+3-3\sqrt{2})}{1^2-(\sqrt{2})^2}\\\\C=\dfrac{7+\sqrt{2}}{1-2}\\\\C=\dfrac{7+\sqrt{2}}{-1}[/tex]

[tex]\boxed{C=-7-\sqrt{2}}[/tex]
