125X16用简便方法计算

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

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

25 x 125 x 16 = 25 x 125 x 2 x 8 = (25 x 2) x ( 125 x 8) = 50 x 1000 = 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”。

125X50x16 =125x50x8x2 =(125x8)x(50x2) =1000x100 =100000 行家正解,不明白可以追问!祝您学习进步 满意请点击下面的【选为满意回答】按钮,O(∩_∩)O谢谢

125x16x5 =125x8x2x5 =1000x10 =10000

125×35×16 =125×35×4×4 =500×140 =70000

0.125x16 =0.125x8x2 =1x2 =2

原式 =125x(8x2)x15 =(125x8)x(2x15) =1000x30 =30000 供参考。
