offeer coroana

Answer 1

Buna! Stiu sa l fac decat pe 3.

$11\sqrt{7}-2(5\sqrt{2} + (13\sqrt{7} + 3(8\sqrt{2}-3\sqrt{7})):4)$$11\sqrt{7}-2(5\sqrt{2} + (13\sqrt{7} + 24\sqrt{2} - 9\sqrt{7} ):4)$

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

$11\sqrt{7}-2(5\sqrt{2} +\frac{4\sqrt{7+24\sqrt{2} } }4}$ = se inchide paranteza

$11\sqrt{7}-2(5\sqrt{2} +\frac{4\sqrt{7+6\sqrt{2} } }4}$ = se inchide paranteza

$11\sqrt{7} - 2 (5\sqrt{2} +\sqrt{7} + 6\sqrt{2} )$

$11\sqrt{7} - 2(11\sqrt{2} + \sqrt{7} )$

$11\sqrt{7} -22\sqrt{2} -2\sqrt{7}$

$9\sqrt{7} - 22\sqrt{2}$

Mult succes!
