125x32x8简便计算

=125x8x32=32000

125x32x24=(125x8)x4x24=1000x96=96000

125x32x125=125x8x125x8/2=1000x1000/2=500000

125*32*125=125*4*2*4*125=500*2*500=1000*500=500000

原式=(125*8)*68=1000*68=68000解答完毕,望采纳,谢谢

用乘法交换律 先计算125*8=1000 再与32相乘得32000 所以原式=125*8*32=1000*32=32000 祝好运

125x32x75=125x8x4x75=1000x300=300000

125x78x8 =125x8x78=1000x78=78000

125x32x0.25 解:=125x(4x8)x0.25=125x8x(4x0.25)=1000x1=1000 祝学习进步.

125*(4*8)*125 =125*4*(8*125) =500*1000 =500000
