Question

$\sqrt[3]{54 } + \sqrt[3]{3} - 5 \sqrt[3]{3}$


​

Answer 1

Resposta:

$3\sqrt[3]{2} -4\sqrt[3]{3}$

Explicação passo-a-passo:

$\sqrt[3]{54} = \sqrt[3]{3^{2} * 2} = 3\sqrt[3]{2} \\\sqrt[3]{3} - 5\sqrt[3]{3} = -4\sqrt[3]{3}$

então:

$\sqrt[3]{54} + \sqrt[3]{3} - 5\sqrt[3]{3} = 3\sqrt[3]{2} -4\sqrt[3]{3}$
