25x16x125简便运算

25X16X125 =25X4X4X125 =100X500 =500000 或25X16X125 =25X2X8X125 =50X1000 =500000 常见化简算式,应牢记: 125X8=1000 25X4=100

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

25×16×125的简便计算 =25x(2x8)x125 =25x2x(8x125) =50x1000 =50000 祝天天向上。

125×16×5 =125×(8×2)×5 =(125×8)×(2×5) =1000×10 =10000 25×32×125 =25×(4×8)×125 =(25×4)×(8×125) =100×1000 =100000

25×16×125 =(25x4)x(4x125) =100x500 =50000

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

125×25x16 =125×25x8x2 =(125x8)x(25x2) =1000x50 =50000

25x160x125 =25x4x8x5x125 =100x(8x125)x5 =100x1000x5 =500000 祝学习进步。

68×0.11+8.9×6.8 =6.8×(1.1+8.9) =6.8×10 =68
