me ajudem por favor ​

Answer 1

Resposta:

1-

a) -3

b) -3

c) -6

d) -1

2-

a) -2

b) -9

Explicação passo-a-passo:

1- a)

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

b)

$\sqrt[5]{-243} =\\-\sqrt[5]{243} =\\-\sqrt[5]{3^{5} } =\\-3$

c)

$\sqrt[3]{-216}=\\-\sqrt[3]{216}=\\-\sqrt[3]{6^{3} }=\\-6$

d)

$\sqrt[7]{-1} =\\-\sqrt[7]{1} =\\-1$

2- a)

$\sqrt[3]{-27} - \sqrt[7]{-1} =\\-3-(-1)=\\-3+1=\\-2$

b)

$\sqrt[3]{-216} + \sqrt[5]{-243} =\\-6-3=\\-9$
