A)–6a²b + 8ab –4 + 4a²b + ab –4 =
B) (–a5) . (2a3) =
C) (4x²) . (–2xy) =
D)(4x^2).(2xy)=
E) (12x^6):(6x^4)

Answer 1

Resposta:

Explicação passo-a-passo:

A)–6a²b + 8ab –4 + 4a²b + ab –4 =

R)-2ab^2+9ab-8

B) (–a5) . (2a3) =

R)-2a^8

C) (4x²) . (–2xy) =

R)-8x^3y

D)(4x^2).(2xy)=

R)8x^3y

E) (12x^6):(6x^4)

2x^2
