125x25x8x4等于多少用简便方法计算

=(125x8)x(25x4) =1000x100 =100000

原式 =(125x8)x(25x4) =1000x100 =100000 供参考。

125X4X8x25简便计算 =(125x8)x(4x25) =1000x100 =100000

=125x8x25x4=1000x100=100000

用简便方法计算125X25X4 125X25X4 =125*(25*4) =125*100 =12500

125x25x38x4x8 =125×8×25×4×38 =1000×100×38 =100000×38 =3800000

(125x25)x4 =125×(25×4) =125×100 =12500

是不是: (125+25)x4 =125x4+25x4 =500+100 =600

125×25×4×8 =(125×8)×(25×4) =1000×100 =100000 运用了乘法的交换律与结合律

125x4.8x25 =125x8x0.6x25 =1000x15 =15000
