doar x va rog frumos !​

Answer 1

Răspuns:

$x=\dfrac{2\sqrt{24}*\sqrt{2}}{\sqrt{54}-\sqrt{2}*\sqrt{27}+\sqrt{2}*\sqrt{6}}=\dfrac{2*\sqrt{24} *\sqrt{2} }{\sqrt{54}-\sqrt{54} +\sqrt{12} }= \dfrac{2*\sqrt{24} *\sqrt{2} }{\sqrt{12} }=2\sqrt{2} *\sqrt{\dfrac{24}{12}} = 2\sqrt{2} *\sqrt{2}=2*(\sqrt{2})^{2}=2*2=4.$
