por favor ayudaaaa

Answer 1

Respuesta:

$\left(\sqrt{3}\:-\:\sqrt{2}\right)^2\:+\:\left(\sqrt{3}\:+\:\sqrt{2}\right)^2+\left(\sqrt{5}\:-\:\sqrt{2}\right)\left(\sqrt{5}\:+\:\sqrt{2}\right)\\\\\\=5-2\sqrt{6}+\left(\sqrt{3}+\sqrt{2}\right)^2+\left(\sqrt{5}-\sqrt{2}\right)\left(\sqrt{5}+\sqrt{2}\right)\\=5-2\sqrt{6}+5+2\sqrt{6}+\left(\sqrt{5}-\sqrt{2}\right)\left(\sqrt{5}+\sqrt{2}\right)\\=5-2\sqrt{6}+5+2\sqrt{6}+3\\=13\\\\\\Resultado=13$
