125x16怎样简便计算

125x16 =125x(2x8) =(125X8)x2 =1000x2 =2000

原式 =125x(8x2) =(125x8)x2 =1000x2 =2000 供参考。

125x16x25=(125*4)*(4*25)=500*100=50000

125×16×5 =(125×8)×(2×5) =1000×10 =10000 你好,本题已解答,如果满意 请点右上角“采纳答案”。

25 x 125 x 16 = 25 x 125 x 2 x 8 = (25 x 2) x ( 125 x 8) = 50 x 1000 = 50000

(125×8)×(25×4)×3 =1000×100×3 =300000

原式 =125x16x39 =(125x8)x(2x39) =1000x78 =78000

125x16x5 =125×(8×2)×5 =(125×8)×(2×5) =1000×10 =10000

0.125x16 =0.125x8x2 =1x2 =2

2.5X0.125X16 =2.5X0.125X2X8 =(2.5X2)X(0.125X8) =5X1 =5
