25x16(简便计算)

25x16 =25x4x4 =100x4 =400

25X16=25X4x4 =100X4 =400

=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。

把16分开,4×4

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

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

25x16x125 =25×(4×4)×(25×5) =25×4×4×25×5 =(25×4)×(4×25)×5 =100×100×5 =50000

180÷3÷5+25*4*4 =60÷5+100*4 =12+400 =412

25x4=100; 125x8=1000; 25x16 =25x4x4 =100x4 =400; 25x48 =25x4x12 =100x12 =1200. 供参考。
