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

=25*4*4 =100*4 =400

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

180÷15+25x16 =180÷3÷5+25x4x4 =60÷5+100x4 =12+400 =412
