Answer 1

Răspuns:

Explicație pas cu pas:

$a = |4 \sqrt{3} - 8 | - \frac{ {}^{3 + 2 \sqrt{3} )} 6}{3 - 2 \sqrt{3} }$

$a = 8 - 4 \sqrt{3} - \frac{6(3 + 2 \sqrt{3}) }{(3 - 2 \sqrt{3} )(3 + 2 \sqrt{3}) }$

$a = 8 - 4 \sqrt{3} - \frac{6(3 + 2 \sqrt{3} )}{9 - 12}$

$a = 8 - 4 \sqrt{3} - \frac{ 6(3 + 2 \sqrt{3} )}{ - 3 }$

$a = 8 - 4 \sqrt{3} - [ - 2(3 + 2 \sqrt{3} )]$

$a = 8 - 4 \sqrt{3} - ( - 6 - 4 \sqrt{3} )$

$a = 8 - 4 \sqrt{3}+ 6 + 4 \sqrt{3} = 8 + 6 = \boxed{14}$
