trebuie sa scoti intregii de sub radical
a)
[tex]( \sqrt{486} - \sqrt{48} \times \sqrt{18} ) \times ( \sqrt{24} + \sqrt{8} \times \sqrt{27} )[/tex]
[tex] = (9 \sqrt{6} - 4 \sqrt{3} \times 3 \sqrt{2} ) \times ( 2 \sqrt{6} + 2 \sqrt{2} + 3 \sqrt{3} )[/tex]
[tex] = ( 9 \sqrt{6} - 12 \sqrt{6} ) \times ( 2 \sqrt{6} + 6 \sqrt{6}) [/tex]
[tex] = ( - 3 \sqrt{6} ) \times 8 \sqrt{6} [/tex]
[tex] = - 24 \times 6[/tex]
[tex] = - 144[/tex]
la fel se aplica si la celelalte
