125x(4 8)x25的简便方法怎么做

125x(4+8)x25 =125x12x25 =(125×3)x(4x25) =375×100 =37500

可以

(125x8)x25+125×(4x25) =1000x25+125x100 =25000+12500 =37500

24x2x125x25怎样简算 =(4x6)x2x125x25 =(4x2x125)x(6x25) =1000x150 =150000

答案是: 8x25十4x25=300 先把两个加数和这个因数分别相乘,再相加,就等于答案。

25x64x125 =25x(8x8)x125 =(25x8)x(8x125) =200x1000 =200000

48×125×25 =6×8×125×25 =1000×150 =150000 ~很高兴为你解答疑问,希望你点击采纳答案,谢谢 ~手机用户点击右上角评价,选择【满意,问题已经完美解决】 ~你的认可,是我的动力,谢谢

解答过程: 32×125×25 =4×8×125×25 =(4×25)×(8×125) =100×1000 =100000

40+8=48,48=6*8, 所以125*25*(40+8)= 125*25**(6*8)= 125*8*25*6=1000*150=150000 看着上面采纳那个,哪里简便了啊,就是分配出去,完全不简算嘛~~

125x(4-8)x25 = 125x(-4)x25 = 125x(-4x25) = 125x(-100) = -12500
