25x16(简便计算)

25x16 =25x4x4 =100x4 =400

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

=25*4*16=100*16=1600

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

25X16=25X4x4 =100X4 =400

原式 =(25x4)x(16x5) =100x8x2x5 =800x10 =8000

25×4×(4×125)=100×500=50000

原式 =25x84x25x(4x4) =(25x4)x84x(25x4) =100x84x100 =8400x100 =840000
