Answer 1

raizes cubicas e quadrupla de 81,243,729 

81 = 3⁴
243 = 3⁵
729 = 3⁶

∛81 =∛(3³.3) = 3∛3
⁴√81 =⁴√3⁴ = 3

∛243 = ∛(3³.3²) = 3∛3²
⁴√243= ⁴√(3⁴.3) = 3 ⁴√3

∛729 = ∛(3³.3³) = 3.3 = 9
⁴√729 =⁴√(3⁴.3²) = 3 ⁴√3²

∛2187 = ∛(3³.3³.3) = 9∛3
⁴√2187= ⁴√(3⁴.3³) = 3 ⁴√3³

∛6561 = ∛(3³.3³.3²) = 9∛3²
⁴√6561= ⁴√(3⁴.3⁴) = 9
