简便计算25x16x15

25×16+50×12 =25×2×8+50×12 =50×(8+12) =50×20 =1000

25x16 =25x4x4 =100x4 =400

25X16=25X4x4 =100X4 =400

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

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。

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

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

将64看成4 x 16再进行简算 25 x 64 =25 x 4 x 16 =100 x 16 =1600 希望我的回答对您有帮助,满意请采纳,谢谢。

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