125×14×4×8×25×5×20简便计算

(125*8)*(25*4)*(20*5)*14

125×14×4×8×25×5×20 =(125x8)x(4x25)x(5x20)x14 =1000x100x100x14 =140 000 000 如有帮助请采纳, 如对本题有疑问可追问,Good luck!

先分别算2×125和8×5 2×125×8×5 =250×40 =10000

(125×4)×8=500×8=4000

125×(8+20) =125*8+125*20 =1000+2500 =3500

42×125×8×5 =(42x5)x(125x8) =210x1000 =210000 23×5×2 =23x(5x2) =23x10 =230 25×9×4 =(25x4)x9 =100x9 =900 15×162×2 =(15x2)x162 =30x162 =4860 (250×125)×(4×8) =(250x4)x(125x8) =1000x1000 =1000000 供参考。

=(25x4)x(125x8) =100x1000 =100000

你好 125×(8×14) =(125x8)x14 =1000x14 =14000

125x25x4 =125x100 =12500

(1)25×125×4×8=25×4×(125×8)=100×1000=100000;(2)37×28+37×2=37×(28+2)=37×30=1110;(3)(10+8)×125=10×125+8×125=1250+1000=2250;(4)173+428+27=173+27+428=200+428=628;(5)38×101=38×(100+1)=38×100+38×1=3800+38=3838;...
