Question

repuesta de (3n+5)³=
​

Answer 1

Respuesta:

$27n^3 + 135n^2 + 225n + 125$

Explicación:

(3n+5)³ = $(3n+5)^{2} (3n+5)$

$(3n+5)^{2} = 9n^2 + 2(3n)(5) + 5^2$

$(3n+5)^{2} = 9n^2 + 30n + 25$

$(3n+5) 9n^2 + 30n + 25$

$27n^3 + 90n^2 + 75n + 45n^2 + 150n + 125$

$27n^3 + 135n^2 + 225n + 125$
