Respuesta :

Let the number be x

#1

[tex]\\ \sf\longmapsto x^3=216[/tex]

[tex]\\ \sf\longmapsto x^3=6^3[/tex]

[tex]\\ \sf\longmapsto x=6[/tex]

#2

[tex]\\ \sf\longmapsto \sqrt[3]{27}=3[/tex]

#3

[tex]\\ \sf\longmapsto \sqrt[3]{-8}=2i[/tex]

  • i=√-1

#4

[tex]\\ \sf\longmapsto -\sqrt[3]{125}=-5[/tex]

#5

[tex]\\ \sf\longmapsto -\sqrt[3]{-343}=-7i[/tex]

#6

[tex]\\ \sf\longmapsto \sqrt[3]{\dfrac{27}{1000}}=\dfrac{3}{10}[/tex]
