Răspuns:
[tex]54-27\sqrt{6}+4\sqrt{183}[/tex]
Explicație pas cu pas:
[tex]\sqrt{18}*(\sqrt{288}+\sqrt{162}-\sqrt{243})-\sqrt{12}*(\sqrt{432}-\sqrt{244})[/tex]
[tex]3\sqrt{2}*(12\sqrt{2}+9\sqrt{2}-9\sqrt{3})-2\sqrt{3}*(12\sqrt{3}-2\sqrt{61})[/tex]
[tex]3\sqrt{2}*(21\sqrt{2}-9\sqrt{3})-72+4\sqrt{183}[/tex]
[tex]126-27\sqrt{6}-72+4\sqrt{183}[/tex]
[tex]54-27\sqrt{6}+4\sqrt{183}[/tex]
