Alguem me ajuda ?? Por favor ! Urgentee

Answer 1

Explicação passo-a-passo:

$a)\\ \sqrt[7]{-1} -\sqrt{16} -\sqrt[3]{-64} =\\ \\ -1-4-\sqrt[3]{-(2^6)} =\\ \\ -1-4-(-2^3)=\\ \\ -1-4+8=\\ \\ -5+8=+3\\ \\ b)\\ 10-\sqrt{49} +\sqrt[7]{0} =\\ \\ 10-7+0=+3\\ \\ c)\\ \sqrt[7]{-1} +\sqrt[3]{8} +\sqrt[5]{-32} +\sqrt{64} =\\ \\ -1+\sqrt[3]{2^3} +\sqrt[5]{-(2^5)} +\sqrt{64} =\\ \\ -1+2+(-2)+8=\\ \\ -1+2-2+8=\\ \\ +10-3=+7$

$d)\\ \sqrt{46+\sqrt{1+\sqrt{64} } } =\\ \\ \sqrt{46+\sqrt{1+8} } =\\ \\ \sqrt{46+\sqrt{9} } =\\ \\ \sqrt{46+3} =\\ \\ \sqrt{49} =7\\ \\ e)\\ \sqrt{32+\sqrt{14+\sqrt{1+\sqrt{9} } } } =\\ \\ \sqrt{32+\sqrt{14+\sqrt{1+3} } } =\\ \\ \sqrt{32+\sqrt{14+\sqrt{4} } } =\\ \\ \sqrt{32+\sqrt{14+2} } =\\ \\ \sqrt{32+\sqrt{16} } =\\ \\ \sqrt{32+4} \\ \\ \sqrt{36} =6$
