3.75乘4.23乘36-125乘0.432乘2.8的巧算
3.75乘4.23乘36-125乘0.432乘2.8
=1.25x4.23x108-125x4.32x28
=4.23x1.25x(108-28)
=4.23x1.25x80
=4.23x100
=423
3.75×4.23×36-125×0.432×2.8
=3.75×4.23×36-1.25×4.32×28
=1.25×3×4.23×4×9-1.25×4.32×4×7
=1.25×4.23×4×(3×9-7)
=1.25×4.23×4×20
=1.25×4.23×80
=100×4.23
=423
3.75×4.23×36 - 125×0.432×2.8
= 37.5×4.23×3.6 - 12.5×4.32×2.8
= 4.23×12.5×(3×3.6 - 2.8)
= 4.23×12.5×8
= 4.23×100
= 423
