Question

expressão com raízes

Answer 1

Resposta:

Segue algumas expressões:

$\sqrt{2}+\sqrt{5}-\sqrt{4}+\sqrt{9}$

$\sqrt{2}(\sqrt{2}-\sqrt{3})-\sqrt{6}$

$\sqrt{8}-\sqrt{7}(\sqrt{3}+\sqrt{7})+\sqrt{5}(\sqrt{4}-\sqrt{2})$

Caso precise das respostas:

$\sqrt{2}+\sqrt{5}-\sqrt{4}+\sqrt{9}=\sqrt{2}+\sqrt{5}-\sqrt{2}+\sqrt{3}=\sqrt{5}-\sqrt{3}$

$\sqrt{2}(\sqrt{2}-\sqrt{3})-\sqrt{6}=\sqrt{4}-\sqrt{6}-\sqrt{6}=2-2\sqrt{6}=-2(\sqrt{6}-1 )$

$\sqrt{8}-\sqrt{7}(\sqrt{3}+\sqrt{7})+\sqrt{5}(\sqrt{4}-\sqrt{2})=\sqrt{8}-\sqrt{21}-\sqrt{49}+\sqrt{20}-\sqrt{10}=$

$=2\sqrt{2}-\sqrt{21}-7+2\sqrt{5}-\sqrt{10}$
