25x16(简便计算)

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

25x16 =25x4x4 =100x4 =400

25X16=25X4x4 =100X4 =400

25×16×5 =(25×4)×(4×5) =100×20 =2000 你好,本题已解答,如果满意,请点右上角“采纳答案”,支持一下。

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

25x16x25 =25x4x4x25 =25x4x(4x25) =100x100 =10000

25x(480+25x16) =25x(480+25x4x4) =25x(480+400) =25x880 =25x4x220 =100x220 =22000

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

25x16x5 = (25×4)×(4×5) = 100 ×20 = 2000

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