[tex] \frac{2-2 \sqrt{6} }{3 \sqrt{3} }^{ \sqrt{3} } - \frac{4 \sqrt{6} }{2 \sqrt{2} } ^{ \sqrt{2} } + \frac{3-3 \sqrt{6} }{5- \sqrt{3} } ^{ \sqrt{3} } = \frac{2-6 \sqrt{2} }{9} - \frac{8 \sqrt{2} }{4} + \frac{3-9 \sqrt{2} }{2} [/tex]
Le aducem la acelasi numitor
[tex] \frac{8-24 \sqrt{2} }{36} - \frac{72 \sqrt{2} }{36} + \frac{54-162 \sqrt{2} }{36} = \frac{-210 \sqrt{2} + 62}{36}[/tex]

Media aritmetica:

[tex] a=\frac{5}{3} ^{7} - \frac{3}{7} ^{3} = \frac{35}{21} - \frac{9}{21} = \frac{26}{21} || y= \frac{1}{3}^{7} + \frac{3}{7} ^{3} = \frac{16}{21} => Ma= \frac{\frac{26}{21} + \frac{16}{21} }{2} =1[/tex]
