Question

es unas multiplicaciones:

(-2)×(-1)×(-3)×(-5)=

5×2×(-2)×(-3)×(-2)=

(-2)×(-3)×4×2×1×4=

(-2)×3×2×4×2×1×2=

2×3×2×6×7×(-1)×(-1)=​

Answer 1

Respuesta:

(-2)×(-1)×(-3)×(-5)=

$2 \times 1 \times 3 \times 5$

$2 \times 3 \times 5$

$10 \times 3$

$30$

5×2×(-2)×(-3)×(-2)=

$(5 \times 2 \times 2 \times 3 \times 3$

$- (5 \times {2}^{2} \times 3 \times 3$

$- (5 \times {2}^{2} \times {3}^{2}$

$- (5 \times 4 \times {3}^{2}$

$- (5 \times 4 \times 9)$

$( - 20 \times 9)$

$- 180$

(-2)×(-3)×4×2×1×4=

$( - 2) \times ( - 3) \times 4 \times 2 \times 2$

$2 \times 3 \times 4 \times 2 \times 4$

${2}^{2} \times 3 \times 4 \times 4$

${2}^{2} \times 3 \times {4}^{2}$

$4 \times 3 \times {4}^{2}$

$4 \times 3 \times 16$

$12 \times 16$

$192$
