Question

multiplicación:

(-7) x (-8) x (-6)=


(+9) x ( -10) x (+5)=

Answer 1

Respuesta:

(-7) x (-8) x (-6)=-336

(+9) x ( -10) x (+5)=-450

Answer 2

Respuesta:

1. = -336
2. = -450

Explicación paso a paso:

(-7) x (-8) x (-6)=

$\mathrm{Aplicar\:regla\:}\left(-a\right)\cdot \left(-b\right)\:=\:a\cdot \:b\\\left(-7\right)\left(-8\right)=7\cdot \:8=56\\=56\left(-6\right)\\\\\mathrm{Aplicar\:regla\:}a\cdot \left(-b\right)\:=\:-a\cdot \:b\\56\left(-6\right)=-56\cdot \:6=-336\\=-336$

-----------------------------------------------------------------

(+9) x ( -10) x (+5)=

$\mathrm{Aplicar\:regla\:}\left(a\right)\cdot \left(-b\right)\:=\:-a\cdot \:b\\\left(9\right)\left(-10\right)=-9\cdot \:10=-90\\=-90\left(5\right)\\\\=-450$
