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

原式=12*5*125*8 =60*1000 =60000 12*5刚好是60 125*8刚好是1000 两数相×就是60000 *=×

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。

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”。

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

(125×25)×4 =125×(25×4) =125×100 =12500

(1)125×32×25,=125×8×4×25,=(125×8)×(4×25),=1000×100,=100000;(2)78×103,=78×(100+3),=78×100+78×3,=7800+234,=8034;(3)25×36×11,=25×4×9×11,=(25×4)×(9×11),=100×99,=9900;(4)14×37+63×14,=14×(37+63),=...
