巧算:125x64x25x5

125x8x5x8x25 =1000x40x25 =1000x1000 =1000000

4x(125x25) =4×25×125 =100×125 =12500

=5x25(4x8+4x8)x25 =5x25x(2x4x8)x25 =5x25x25x(2x4x4x2) =(5x2x2)x(25x4)x(25x4) =20x100x100 =200000

125x48x25=125×8×6×25=1000×150=150000

如图

300÷125*25=300÷(125/25)=300÷5=60

两个4乘25等于2乘100等于200

原数等于 8×25+17×25 =200+425 =625 ~回答完毕~ ~结果仅供参考~ ~\(^o^)/~祝学习进步~~~

求解…怎么巧算25X25+25X25 解: 25X25+25X25 =25×25×2 =25×50 =1250

4800x25 =48x25x100 =(40+8)x25x100 =(40x25+8x25)x100 =(1000+200)x100 =120000
