6899怎么算得24

6899计算24有以下解法8/(6/(9+9))(8/6)*(9+9)8/(6/(9+9))(8/6)*(9+9)8/((9-6)/9)(8/(9-6))*98*((9+9)/6)(8*(9+9))/68*(9/(9-6))(8*9)/(9-6)

8*[9/(9-6)]=248/[(9-6)/9]=248/[6/(9+9)]=24

主要有这几种,供参考:8*(9+9)/6=8*18/6=144/6=24;(8*9)/(9-6)=72/3=24;8/(9-6)*9=8/3*9=8*3=24;

你好,可以这样算9*8÷(9-6)=24

(4-9÷9)*8

这几个数字的位置能变吗?具体要求有什么?

1: 8 - (7 - 9) * 82: 8 - ((7 - 9) * 8)3: 8 - (8 * (7 - 9))4: 8 - 8 *(7 - 9)5: 8 + (8 * (9 - 7))6: 8 + 8 *(9 - 7)7: 8 + (9 - 7) * 88: 8 + ((9 - 7) * 8)9: (8 * (9 - 7)) + 810: 8 * (9 - 7) + 811: (9 - 7) * 8 + 812: ((9 - 7) * 8) + 8

用9除以3得3 3乘以5得15 15加上9得二十四

(1*3*24+2*6*48+3*9*72)/(1*2*4+2*4*8+3*6*12) =36(1*2+2*8+6*9)/4(1*2+2*8+6*9) =36/4 =9

8/(3-8/3)=24
