Buna! Stiu sa l fac decat pe 3.

[tex]11\sqrt{7}-2(5\sqrt{2} + (13\sqrt{7} + 3(8\sqrt{2}-3\sqrt{7})):4)\\[/tex][tex]11\sqrt{7}-2(5\sqrt{2} + (13\sqrt{7} + 24\sqrt{2} - 9\sqrt{7} ):4)\\[/tex]

[tex]11\sqrt{7} - 2(5\sqrt{2}+(4\sqrt{7}+24\sqrt{2}) : 4[/tex] = dupa 4 se inchide paranteza am uitat sa pun

[tex]11\sqrt{7}-2(5\sqrt{2} +\frac{4\sqrt{7+24\sqrt{2} } }4}[/tex] = se inchide paranteza

[tex]11\sqrt{7}-2(5\sqrt{2} +\frac{4\sqrt{7+6\sqrt{2} } }4}[/tex] = se inchide paranteza

[tex]11\sqrt{7} - 2 (5\sqrt{2} +\sqrt{7} + 6\sqrt{2} )[/tex]

[tex]11\sqrt{7} - 2(11\sqrt{2} + \sqrt{7} )[/tex]

[tex]11\sqrt{7} -22\sqrt{2} -2\sqrt{7}[/tex]

[tex]9\sqrt{7} - 22\sqrt{2}[/tex]

Mult succes!
