Answer 1

Resposta:

Olá,

Substituindo os valores de x e y, temos:

= $2\cdot 1^4\cdot \left(-1\right)^3-3\cdot 1^3\cdot \left(-1\right)-2\cdot 1^3+\left(1\right)^3+4\cdot 1^2\cdot \left(-1\right)^5$

= $2\cdot \:1\cdot \left(-1\right)-3\cdot \:1\cdot \left(-1\right)-2\cdot \:1+1+4\cdot \:1\cdot \left(-1\right)$

= $-2-3\cdot \:1\cdot \left(-1\right)-2\cdot \:1+1+4\cdot \:1\cdot \left(-1\right)$

= $-2-\left(-3\right)-2\cdot \:1+1+4\cdot \:1\cdot \left(-1\right)$

= $-2-\left(-3\right)-2+1+4\cdot \:1\cdot \left(-1\right)$

= $-2-\left(-3\right)-2+1-4$

= -4
