25x32x125简便计算？

Answer 1

你好，25 x 32 x 125的简便计算为：原式亩肢凯 = 25 x 4 x 8 x 125 = (25 x 4 ) x (8 x 125) = 100 x 1000 = 100000

解题思路如下：

利用改数法，饥孙将数字32拆分成 4 x 8后，而25 x 4 = 100，125 x 8 = 1000。所以，原式可转化为： (25 x 4 ) x (8 x 125) = 100 x 1000 = 100000

知识迅唤拓展：

简便计算需熟记的算式：25 x 4 = 100； 25 x 8 = 200; 125 x 8 = 1000; 125 x 4 = 500

Answer 2

=25*(4*8)*125
=(25*4)*(8*125)
=100*1000
=100000
