Question

efetue as multiplicaçoes algebricas a)(12x²).(3x) b)(-5xyz).(-xy) c)(7a).(2b).(2ab) d)(-9x²y).(-2xy²).(2z) e)(x/5).(3x) f)(4x/5).(y/3) ME AJUDE POR FAVOR AMANHA TENHO QUE ENTREGAR BEM CEDO

Answer 1

Resposta:

Olá, tudo bem?

A) (12x²) × (3x) =

12x² × 3x

36x³

B) (- 5xyz) × (- xy) =

5xyzxy

5x²y²z

C) (7a) × (2b) × (2ab) =

7a × 2b × 2ab

28a²b²

D) (- 9x²y) × (- 2xy²) × (2z) =

9x²y × 2xz² × 2z

36x³y³z

E) (x/5) × (3x) =

x/5 × 3x

3x²/5

F) (4x/5) × (y/3) =

4xy/5 × 3

4xy/15

Espero ter ajudado, bons estudos :)
