Explicație pas cu pas:
[tex]a = |4 \sqrt{3} - 8 | - \frac{ {}^{3 + 2 \sqrt{3} )} 6}{3 - 2 \sqrt{3} } \\ [/tex]
[tex]a = 8 - 4 \sqrt{3} - \frac{6(3 + 2 \sqrt{3}) }{(3 - 2 \sqrt{3} )(3 + 2 \sqrt{3}) } \\ [/tex]
[tex]a = 8 - 4 \sqrt{3} - \frac{6(3 + 2 \sqrt{3} )}{9 - 12} \\ [/tex]
[tex]a = 8 - 4 \sqrt{3} - \frac{ 6(3 + 2 \sqrt{3} )}{ - 3 } \\ [/tex]
[tex]a = 8 - 4 \sqrt{3} - [ - 2(3 + 2 \sqrt{3} )] \\ [/tex]
[tex]a = 8 - 4 \sqrt{3} - ( - 6 - 4 \sqrt{3} )[/tex]
[tex]a = 8 - 4 \sqrt{3}+ 6 + 4 \sqrt{3} = 8 + 6 = \boxed{14} \\ [/tex]
