50×0.8×0.04×1.25×0.02×250简便计算

50×0.8×0.04×1.25×0.02×250简便计算

50×0.8×0.04×1.25×0.02×250
=50×0.02×250×0.04×1.25×0.8
=1×10×1
=10

50×0.8×0.04×1.25×0.02×250
=(50×0.02)×(0.8×1.25)×(0.04×250)
=1×1×10
=10

原式=(50×0.02)×(0.8×1.25)×0.04×250)
=1×1×10
=10

50×0.02×0.8×1.25×0.04×250=0.1×1x10=1

50×0.8×0.04×1.25×0.02×250
=(50×0.02)×(0.8×1.25)×(0.04×250)
=1×1x10
=10
