n.m = 2
(m + n) = 4 Elevamos ambos miembros al cuadrado
(m + n)² = 4²
m² + 2mn + n² = 16 Pero n . m = 2
m² + 2 * 2 + n² = 16
m² + 4 + n² = 16
m² + n ² = 16 - 4
m² + n² = 12
Suma de cubos
n³ + m³ = (n + m)(n² - n . m + m²)
n³ + m³ = 4 ( (n² + m²) - n .m)
n³ + m³ = 4(12 - 2)
n³ + m³ = 4 * 10
n³ + m³ = 40
Respuesta.
n³ + m³ = 40
