CON RESOLUCION PORFA

Answer 1

Respuesta:

A= -3

B= -4

C= -14

D= -47

E=-20

Explicación paso a paso:

A=$\sqrt[3]{27}+3\sqrt[3]{-8}$

=>3+3(-2)

=> 3-6= -3

B=-[$-\sqrt[5]{243} - \sqrt[3]{-343}$]

=>-[-3 - (-7)]

=>- [-3+7] = -4

C= $-7 -7\sqrt[7]{1}+2\sqrt[9]{0}$

=> -7 -7(1) +2 (0)

=> -7 -7+0 = -14

D=$\sqrt[7]{-128} - 5\sqrt{81}$

=> -2-5(9)

=>-2-45= -47

E=$-2\sqrt{9} - 7\sqrt{49}$

=> -2(3) - 7(7)

=> -6 -14 = -20
