Question

Calcule as potências:
a) ( + 5)^3=

b) ( + 12)^3=

c) ( – 17)^2=

d) ( + 2/3)^– 3= e) ( + 4) ^3=

Vocês poderiam me ajudar?

Answer 1

Explicação passo-a-passo:

$a)\\ (+5)^3=(+5)(+5)(+5)=+125\\ \\ b)\\ \\ (+12)^3=(+12)(+12)(+12)=1728\\ \\ c)\\ (-17)^2=(-17)(-17)=+289\\ \\ d)\\ ({2\over3})^{-3}=({3\over2})^3=({3\over2})({3\over2})({3\over2}={27\over8}\\ \\ e)\\ (+4)^3=(+4)(+4)(+4)=+64$
