Question

(1-x) elevado a 3/2 = 0,39 como resolver ?

Answer 1

$\displaystyle (1-\text x)^{\frac{3}{2}} = 0,39 \\\\ \sqrt[2]{(1-\text x)^3} = \frac{39}{100} \\\\ \text{elevando ao quadrado dos dois lados} : \\\\ (1-\text x)^3 = 0,1521 \\\\ \text{tirando a raiz cubida dos dois lados }: \\\\ 1-\text x = \sqrt[3]{0,1521} \\\\ \huge\boxed{\text x = 1 -\sqrt[3]{0,1521}}\checkmark \\\\\\ \text{ou} \\\\\\\ \huge\boxed{\text x = 0.467}\checkmark$
