Respuesta:

$\left(2x^3\:+\:4x^2\right)^3\\\\\\\mathrm{Aplicar\:la\:f0rmula\:del\:binomio\:al\:cubo}:\quad \left(a+b\right)^3=a^3+3a^2b+3ab^2+b^3\\a=2x^3,\:\:b=4x^2\\=\left(2x^3\right)^3+3\left(2x^3\right)^2\cdot \:4x^2+3\cdot \:2x^3\left(4x^2\right)^2+\left(4x^2\right)^3\\\\=8x^9+48x^8+96x^7+64x^6$
