alguém mim ajuda porfravor ​

Answer 1

Resposta:

$\sqrt{32} +4\sqrt{8} -\sqrt{50} -(\sqrt{2} )^{3} =\\ \\ \sqrt{4.8} +4\sqrt{8} -\sqrt{25.2} -(\sqrt[2]{2^{2}.2^{1} } )=\\ \\ \sqrt[2]{2^{2}.2^{2}.2^{1} } +4\sqrt[2]{2^{2} .2^{2}.2^{1} } -\sqrt[2]{5^{2}.2 } -2\sqrt{2} =\\ \\ 2.2.\sqrt{2} +4.2.2.\sqrt{2}-5.\sqrt{2} -2\sqrt{2} =\\ \\ 4\sqrt{2} +16\sqrt{2} -5\sqrt{2}-2\sqrt{2} =\\ \\ 13\sqrt{2}$
