Oblicz wartość wyrażeniaOblicz wartość wyrażenia.... Question from @liluse

$(\sqrt{3-\sqrt{5}} + (\sqrt{3+\sqrt{5}})^{2}=\\ =(\sqrt{3-\sqrt5})^2+2\sqrt{3-\sqrt5}\cdot\sqrt{3+\sqrt5} +(\sqrt{3+\sqrt5})^2=\\ =3-\sqrt5+2\sqrt{9-5}+3+\sqrt5=6+2\sqrt4=6+2\cdot2=10\\ \\ (\sqrt{6\sqrt{2}+11}-\sqrt{11-6\sqrt{2}})^{2}=\\ =(\sqrt{11+6\sqrt2})^2-2\sqrt{11+6\sqrt2}\cdot\sqrt{11-6\sqrt2}+(\sqrt{11-6\sqrt2})^2=\\ =11+6\sqrt2-2\sqrt{11^2-(6\sqrt2)^2}+11-6\sqrt2=\\ =22-2\sqrt{121-36\cdot2}=22-2\sqrt{121-72}=\\ =22-2\sqrt{49}=22-2\cdot7=22-14=8$
