125x16怎样简便计算

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

125×16×7 =125×(8×2)×7 =(125×8)×(2×7) =1000×14 =14000

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”。

125*8*2*50 =1000*100 =100000

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

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

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

原式 =125x(8x2) =(125x8)x2 =1000x2 =2000
