你好很高兴为您解答4*50=2006*70=420200*420=84000望采纳!

4x70x50x60= 40x50x70x60=2000x4200=8400000

4x70x50x6=(4 x 50) x(70 x 6)=200x420=84000

4*70*50*6=4*50*6*70=200*420=84000

4x60x50x80=(4*50)*(60*80)=200*4800=960000或者:4x60x50x80=(4x60)x(50x80)=240*4000=960000

4*60*50*8=(4*50)*(60*8)=200*480=96000

4x60x50x8=(4x60)x(50x8)=240*400=96000

4x60x50x8=4x50x60x8=200x480=96000

97x50x6的乘法的简便方法 100*300-900

24xx7x4x6 =[25-1]x4x7x6 =25x4x7x6-1x4x7x6 =4200-42x4 =4200-168 =4032
