Explicație pas cu pas:
[tex] \frac{ {}^{ \sqrt{3}) } 2 \sqrt{3} + 9}{ \sqrt{3} } - \sqrt{27} \\ [/tex]
[tex] = \frac{(2 \sqrt{3} + 9) \sqrt{3} }{3} - 3 \sqrt{3} \\ [/tex]
[tex] = \frac{6 + 9 \sqrt{3} }{3} - 3 \sqrt{3} \\ [/tex]
[tex] = \frac{\not3(2 + 3 \sqrt{3} )}{\not3} - 3 \sqrt{3} \\ [/tex]
[tex] = 2 + 3 \sqrt{3} - 3 \sqrt{3} = \blue{\boxed{2}} [/tex]
