$[(\sqrt[3]{27} + \sqrt[3]{125}) \div \sqrt[3]{64} - \sqrt[3]{8} + \sqrt[3]{1} ]$
​

Answer 1

Explicação passo-a-passo:

Calculando o valor das raízes:

$\sqrt[3]{27}=3\ , \ pois\ 3.3.3=27 \\\sqrt[3]{125}=5\ , \ pois\ 5.5.5=125 \\\sqrt[3]{64}=4\ , \ pois\ 4.4.4=64 \\\sqrt[3]{8}=2\ , \ pois\ 2.2.2=8 \\\sqrt[3]{1}=1\ , \ pois\ 1.1.1=1$

Resolvendo a expressão:

$E=[(\sqrt[3]{27}+\sqrt[3]{125} )\div\sqrt[3]{64}-\sqrt[3]{8}+\sqrt[3]{1}]\\\\E=[(3+5 )\div 4-2+1]\\\\E=[8\div 4-2+1]\\\\E=[2-2+1]\\\\\boxed{\boxed{E=1}}$
