Question

Complete com (C) de certo ou (E) de errado :
( ) (5.3)^3=5^3.3^3
( )x^3.x^3.x^2.x^2=x^10
( ) (5+3)^3=5^3+3^3
( )x^15:x^10:x^2=x^3

Answer 1

Explicação passo-a-passo:

( C ) (5.3)³ = 5³ x 3³

( C ) x³ . x³ . x² . x² = x¹⁰

( E ) (5 + 3)³ = 5³+ 3³

(5 + 3)³ = 8³ = 512

5³ + 3³ = 125 + 27 = 152

( C ) x¹⁵ : x¹⁰ : x² = x³
