125×14×4×8×25×5×20简便计算

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

125×(8×14)×5 =125×8×(14×5) =1000×70 =70000 很高兴为你解答满意望采纳

125%×25%×4×8 =(125% ×8) ×(25%×4) =10 ×1 =10

8×25×125×4 =(8×125)×(25×4) =1000×100 =100000 你好,本题已解答,如果满意 请点右上角“采纳答案”。

(1)25×125×4×8=(25×4)×(125×8)=100×1000=100000;(2)21+254+79+46 =(21+79)+(254+46)=100+300=400;(3)3.2+8.3+5.8+1.7=(3.2+5.8)+(8.3+1.7)=9+10=19;(4)7-0.55-1.44=7-(0.55+1.44)=7-1.99=5.01;(5)2.7+0.3-2.7+0.3=...

8×(125+25)×4 =8*125*4+25*4*8 =4000+800 =4800

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。

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

原式等于 25×4×125×8 =100×1000 =100000 ~回答完毕~ ~\(^o^)/~祝学习进步~~~

24.5×4+125×8 =(25-0.5)×4+1000 =25×4-0.5×4+1000 =100-2+1000 =1098
