Question

(5m+2n)³ ayuda xfis para ahorita

Answer 1

Explicación paso a paso:

(5m+2n)³

• usaremos el producto notable "binomio al cubo"

-------------------------------------------------

(a+b)³ = a³+3a²b+3ab²+b³

-------------------------------------------------

= (5m)³+3(5m)²(2n)+3(5m)(2n)²+(2n)³

• repartimos los exponentes
• realizamos la multiplicación

=125m³+150m²n+60mn²+8n³

Answer 2

(5m+2n)^3
(5m)^3 + (2n)^3 +3(5m +2n)(10mn)
(125)m^3 + (8)n^3 + 30mn(5m+2n)
125(m^3) + 8(n^3) + 150(m^2)n+69m(n^2)
