$\sf Veja\:Abaixo$

Para x=2,y=-2 e m=-1

Logo:

A)

$\boxed{\begin{array}{lr} \large \sf x^{3} m+14x^{2}m^{2} \\ \\ \large \sf 2^{3}\times(-1)+14\times2^{2}\times(-1)^{2} \\ \\ \large \sf 8\times(-1)+14\times4\times1 \\ \\ \large \sf -8+56 \\ \\ \large \sf 48 \end{array}}$

Resposta:

48

B)

$\boxed{\begin{array}{lr} \large \sf x^{5} y-x^{3} y^{4} \\ \\ \large \sf 2^{5}\times(-2)-2^{3} \times(-2)^{4} \\ \\ \large \sf 32\times(-2)-8\times16 \\ \\ \large \sf -64-128 \\ \\ \large \sf -192 \end{array}}$

Resposta:

-192

Bons estudos =)
