= 5.6*69.32 + 2*0.05*69.32 + 69.32*10*0.43 + 0.2*0.43
= 5.7*69.32+4.3*69.32+0.086
= 10*69.32 + 0.086
= 693.2 +0.086
= 693.286

9999*7778 + 3333 *6666
把3333*6666 拆掉 变成 3333 * 2222 *3
就变成 9999*2222
9999 x 7778 + 9999 x 2222
=9999 x (7778+2222)
=9999 x 10000
答案 99990000
56*69.32 + 138.64 *0.05 +693.2*0.43
138.64 *0.05=6.932
所以式子变成 56 x 69.32 + 1 x6.932 + 0.43x693.2
5.6 x 693.2 +0.01 x 693.2 +0.43 *693.2
合并693.2 (5.6 +0.01 +0.43)
693.2 *(6.04) = 4186.928
第二题数字有点奇怪 你有抄错吗
