(n⁴-3m²n²+7n⁴)(-4m³x)
ayuda​

Answer 1

Simplificar: $\mathrm{}\:\left(n^4-3m^2n^2+7n^4\right)\left(-4m^3x\right):\quad -4xm^3\left(8n^4-3m^2n^2\right)$

$\left(n^4-3m^2n^2+7n^4\right)\left(-4m^3x\right)$

Aplicar la propiedad: $\:a\left(-b\right)=-ab$

$\left(n^4-3m^2n^2+7n^4\right)\left(-4m^3x\right)=-\left(n^4-3m^2n^2+7n^4\right)\cdot \:4m^3x$

$=-\left(n^4-3m^2n^2+7n^4\right)\cdot \:4m^3x$

$=-4xm^3\left(n^4-3m^2n^2+7n^4\right)$

Simplificar: $n^{4} -3m^{2} n^{2} +7n^{4}: 8n^{4}-3m^{2} n^{2}$

$=-4xm^3\left(8n^4-3m^2n^2\right)$
