Explicație pas cu pas:
[tex]8 \sqrt{3} + 2 \sqrt{12} - \sqrt{27} [/tex]
[tex] = 8 \sqrt{3} + 2 \sqrt{2 {}^{2} \times 3} - \sqrt{3 {}^{3} } [/tex]
[tex] = 8\sqrt{3} + 2 \times 2 \sqrt{3} - \sqrt{3 {}^{2} \times 3 } [/tex]
[tex] = 8 \sqrt{3} + 4 \sqrt{3} - 3 \sqrt{3} [/tex]
[tex] = (8 + 4 - 3) \sqrt{3} = \boxed{9 \sqrt{3} }[/tex]
