Question

$\sqrt[3]{8} + 5 \sqrt[3]{8} - 3 \sqrt[3]{8} =$
$6 \sqrt[5]{32} + 4 \sqrt[5]{32} - 2 \sqrt[5]{32} =$
​

Answer 1

Resposta:

a.

$\sqrt[3]{8} + 5\sqrt[3]{8} - 3 \sqrt[3]{8} = \\\\2 + 5 * 2 - 3 * 2 =\\\\2 + 10 -6 = \\12 - 6 = 6$

b.

$6\sqrt[5]{32} + 4\sqrt[5]{32} - 2\sqrt[5]{32} = \\\\6 * 2 + 4 * 2 - 2 * 2 =\\\\12 +10 - 4 =\\\\22 - 4 =\\\\18$

Answer 2

Oie, Td Bom?!

$\sqrt[3]{8} + 5 \sqrt[3]{8} - 3 \sqrt[3]{8}$

$2 + 5 \times 2 - 3 \times 2$

$2(1 + 5 - 3)$

$2 \times 3$

$6$

___

$6 \sqrt[5]{32} + 4 \sqrt[5]{32} - 2 \sqrt[5]{32}$

$6 \times 2 + 4 \times 2 - 2 \times 2$

$2(6 + 4 - 2)$

$2 \times 8$

$16$
