Por favor con procedimientos necesito aprobar

Answer 1

Respuesta:

A. a^3+9a^2+27a+27

B. m^3-6m^2n+12mn^2-8n^3

C. 27d^3+135d^2p+225dp^2+125p^3

Explicación paso a paso:

Pregunta A

(a+3)^3

Ocupando formula

a^3+3a^2×3×+3a×3^2+3^3

a^3+9a^+3a×9+27

a^3+9a^2+27a+27

Pregunta B

(m-2n)^3

Usando la formula

m^3-3m^2×2n+3m×(2n)^2-(2n)^3

m^3-6m^2n+3m×4n^2-8n^3

m^3-6m^2n+12mn^2-8n^3

Pregunta C

(3d+5p)^3

Ocupando la formula

3d^3+3×3d^2×5p+3×3d×5p^2+5p^3

27d^3+3×9d^2×5p+3×3d×25p^2+125p^3

27d^3+135d^2p+225dp^2+125p^3
