Answer 1

Explicação passo-a-passo:

$\sqrt{ {c}^{2} } = {c}^{ \frac{2}{2} } = {c}^{1} = c$

$- \sqrt{ {a}^{4} } = - {a}^{ \frac{4}{2} } = - {a}^{2}$

$\sqrt[3]{ - 0.001} = \sqrt[3]{( - 0.1)^{3} } = ( - 0.1)^{ \frac{3}{3} } = ( - 0.1)^{1} = - 0.1$

$- \sqrt[3]{ - 8} = - \sqrt[3]{( - 2)^{3} } = - ( - 2)^{ \frac{3}{3} } = - ( - 2)^{1} = - ( - 2) = 2$
