Answer 1

Rezolvare:

$\frac{1}{16} -\frac{4\sqrt{2} }{4} + 8 + 4 + \frac{4\sqrt{2} }{4} + \frac{2}{16} -3(\frac{1}{4}-\sqrt{3})(\frac{1}{4}+\sqrt{3})=\\\frac{1}{16} - \sqrt{2} + 8 + 4 + \sqrt{2} + \frac{2}{16} -3(\frac{1}{16} - 3)=\\\frac{1}{16} + 8 + 4 + \frac{2}{16} -3(-\frac{47}{16})=\\\frac{1}{16} + 8 + 4 +\frac{2}{16} + \frac{141}{16} =\\9+12 =\\21$
