Resposta:
[tex]a)\left(1+\sqrt{10}\right)^2=11+2\sqrt{10}[/tex]
[tex]b)\left(3-\sqrt{\sqrt{5}}\right)^2=9-6\sqrt[4]{5}+\sqrt{5}[/tex]
[tex]c)\left(\sqrt{7}+\sqrt{2}\right)^2=9+2\sqrt{14}[/tex]
[tex]d)\left(\sqrt{1}0-\sqrt{7}\right)^2=\left(\sqrt{1}\cdot \:0\right)^2-2\sqrt{1}\cdot \:0\cdot \sqrt{7}+\left(\sqrt{7}\right)^2=7[/tex]
