4x125x25x8简便计算

4x125x25x8=125*8*(25*4)=1000*100=100000

利用乘法交换律和乘法结合律算简便4x125x5x8=(4x5)x(125x8)=20x1000=20000

(4+125)x25x8=4X25X8+125X8X25=800+25000=25800

(125十125十125十125)X25X8=125X4X25X8=125X8X(25X4)=1000X100=100000希望能帮到你

5x9x125x2x8 =(5x2)x(8x125)x9 =10x1000x9 =900005x9x125x2x8 =(5x2)x(8x125)x9 =10x1000x9 =90000

125x25x(8十40)求解125x25x(8十40)=(125*8*25)+(125*25*40)=25*1000+125*1000=25000+125000=15000

125x25x16=125*25*4*4=125*4+25*4=600*100=60000

125x25x96=125x25x(8x4x3)=(125x8)x(25x4)x3=1000x100x3=300000

用简便方法计算4x125x50=4x50x125=200x125=25000

125*45*8=(125*8)*45=1000*45=45000
