Question

calcule as raízes a seguir
$\sqrt{16}$
$\sqrt[5]{32}$
$\sqrt[4]{16}$
$- \sqrt[4]{81}$
$\sqrt[3]{ - 27}$
$\sqrt[3]{ - 1.000}$
$\sqrt[3]{3.375}$
$- \sqrt{6.561}$
​

Answer 1

$\sqrt{16} = \sqrt{ {4}^{2} } = 4$

$\sqrt[5]{32} = \sqrt[5]{ {2}^{5} } = 2$

$\sqrt[4]{16} = \sqrt[4]{ {2}^{4} } = 2$

$- \sqrt[4]{81} = - \sqrt[4]{ {3}^{4} } = - 3$

$\sqrt[3]{ - 27} = - \sqrt[3]{27} = - \sqrt[3]{ {3}^{3} } = - 3$

$\sqrt[3]{ - 1000} = - \sqrt[3]{1000} = - \sqrt[3]{ {10}^{ 3} } = - 10$

$\sqrt[3]{3375} = \sqrt[3]{ {15}^{3} } = 15$

$- \sqrt{6561} = - \sqrt{ {81}^{2} } = - 81$
