简便计算25x16x15

25x16 =25x4x4 =100x4 =400

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

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。

25X5X16 =(25×4)×(5×4) =100×20 =2000

25*4*2*15*2 =100*2*30 =6000 望采纳,

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

用乘法交换律 25x16=16x25=4x4X25=4x100=400 乘法结合律 25x16=25X(4x4)=(25x4)x4=400

496+25×16 =496+25×4×4 =496+400 =896 你好,本题已解答,如果满意 请点右上角“采纳答案”。

25x84+25x16 =25x(84+16) =25x100 =2500
