Answer 2

Explicație pas cu pas:

a)

$a=(\frac{4\sqrt{3} }{3} -\frac{7\sqrt{2} }{2} )*\sqrt{6} +7\sqrt{3} -12$

$a=\frac{8\sqrt{3} -21\sqrt{2}}{6}*\sqrt{6} +7\sqrt{3} -12$

$a=\frac{\sqrt{6}(8\sqrt{3} -21\sqrt{2}) +42\sqrt{3}}{6}-12$

$a=\frac{24\sqrt{2} -42\sqrt{3} +42\sqrt{3}}{6}-12$

$a=\frac{24\sqrt{2}}{6} -12$

$a=4\sqrt{2} -12$

$a=4(\sqrt{2} -3)$

b)

$b=\sqrt{36+64} -\frac{8\sqrt{2} }{2}$

$b=\sqrt{100} -4\sqrt{2}$

$b=10 -4\sqrt{2}$

$(a+b)^{10} =(4\sqrt{2}-12+10-4\sqrt{2} )^{10} =(-2)^{10} =1024$
