3479,用3479这4个数怎样运算得到24

1,用3479这4个数怎样运算得到249-7=22x4=83x8=24!3x4x(9-7)请采纳谢谢没看懂什么意思?
2,用3479四个数加减乘除等于24(9-7)×3×41.﹙3×9﹚-﹙7-4﹚ 2.4×[3×﹙9-7﹚] 3.4+[﹙3×9﹚-7]【3479,用3479这4个数怎样运算得到24】
3,CZ3479 航班在哪里中转每周二、四、六的CZ3479/80航班调整为:15点3 5分从郑州起飞,16点55分到达重庆,17点50分从重庆起飞,19点10分到达南宁;19点50分从南宁起飞返回 , 21点到达重庆,21点50分从重庆起飞,23点10分到达郑州 。重庆中转 。每天执飞的班机不一定是一样的,今天的班机,中间安全出口分别是40、41排 。
4,3479得数24有几个算式给出4个数字,所给数字均为有整数(1至13之间),用加、减、乘、除(可加括号)把给出的数算成24,每个数必须用一次且只能用一次,先算出结果者获胜 。例:3、8、8、9答案:3×8÷(9—8)=24答案不唯一3x[4x(9-7)]=244x[3x(9-7)]=24用3,4,7,9算24点 , 共有34种算法5,3479算24点(9-7)x4x3=243*(4+7)-9=2453*(4+7)-9=3*11-9=33-9=24;3*4*(9-7)=12*2=24;3*9+4-7=27+4-7=31-7=24;9*(7-4)-3=9*3-3=27-3=24;……供参考 。(9-7)×4×3=246,3479算二十四4*3*(9-7)1:(3 × (4 + 7)) - 92:3 × (4 + 7) - 93:3 × (4 × (9 - 7))4:3 × 4 ×(9 - 7)5:(3 × 4) × (9 - 7)6:(3 × (7 + 4)) - 97:3 × (7 + 4) - 98:3 × 9 + 4 - 79:(3 × 9) + 4 - 710:(3 × 9 + 4) - 711:((3 × 9) + 4) - 712:3 × 9 +(4 - 7)13:(3 × 9) + (4 - 7)14:3 × 9 - 7 + 415:(3 × 9) - 7 + 416:(3 × 9 - 7) + 417:((3 × 9) - 7) + 418:3 × 9 -(7 - 4)19:(3 × 9) - (7 - 4)20:(3 × (9 - 7)) × 421:3 × (9 - 7) × 422:3 × ((9 - 7) × 4)23:4 + 3 × 9 - 724:(4 + 3 × 9) - 725:(4 + (3 × 9)) - 726:4 + (3 × 9) - 727:4 + (3 × 9 - 7)28:4 + ((3 × 9) - 7)29:4 × (3 × (9 - 7))30:4 × 3 ×(9 - 7)31:(4 × 3) × (9 - 7)32:(4 + 7) × 3 - 933:((4 + 7) × 3) - 934:4 - 7 + 3 × 935:(4 - 7) + 3 × 936:4 - 7 +(3 × 9)37:(4 - 7) + (3 × 9)38:4 - (7 - 3 × 9)39:4 - (7 - (3 × 9))40:4 - 7 + 9 × 341:(4 - 7) + 9 × 342:4 - 7 +(9 × 3)43:(4 - 7) + (9 × 3)44:4 - (7 - 9 × 3)45:4 - (7 - (9 × 3))46:4 + 9 × 3 - 747:(4 + 9 × 3) - 748:(4 + (9 × 3)) - 749:4 + (9 × 3) - 750:4 + (9 × 3 - 7)51:4 + ((9 × 3) - 7)52:(4 × (9 - 7)) × 353:4 × (9 - 7) × 354:4 × ((9 - 7) × 3)55:(7 + 4) × 3 - 956:((7 + 4) × 3) - 957:(7 - 4) × 9 - 358:((7 - 4) × 9) - 359:9 × 3 + 4 - 760:(9 × 3) + 4 - 761:(9 × 3 + 4) - 762:((9 × 3) + 4) - 763:9 × 3 +(4 - 7)64:(9 × 3) + (4 - 7)65:9 × 3 - 7 + 466:(9 × 3) - 7 + 467:(9 × 3 - 7) + 468:((9 × 3) - 7) + 469:9 × 3 -(7 - 4)70:(9 × 3) - (7 - 4)71:(9 - 7) × 3 × 472:((9 - 7) × 3) × 473:(9 - 7) × (3 × 4)74:(9 - 7) × 4 × 375:((9 - 7) × 4) × 376:(9 - 7) × (4 × 3)77:(9 × (7 - 4)) - 378:9 × (7 - 4) - 33*9-7+4=243*4*(9-7)=241:(3 × (4 + 7)) - 92:3 × (4 + 7) - 93:3 × (4 × (9 - 7))4:3 × 4 ×(9 - 7)5:(3 × 4) × (9 - 7)6:(3 × (7 + 4)) - 97:3 × (7 + 4) - 98:3 × 9 + 4 - 79:(3 × 9) + 4 - 710:(3 × 9 + 4) - 711:((3 × 9) + 4) - 712:3 × 9 +(4 - 7)13:(3 × 9) + (4 - 7)14:3 × 9 - 7 + 415:(3 × 9) - 7 + 416:(3 × 9 - 7) + 417:((3 × 9) - 7) + 418:3 × 9 -(7 - 4)19:(3 × 9) - (7 - 4)20:(3 × (9 - 7)) × 421:3 × (9 - 7) × 422:3 × ((9 - 7) × 4)23:4 + 3 × 9 - 724:(4 + 3 × 9) - 725:(4 + (3 × 9)) - 726:4 + (3 × 9) - 727:4 + (3 × 9 - 7)28:4 + ((3 × 9) - 7)29:4 × (3 × (9 - 7))30:4 × 3 ×(9 - 7)31:(4 × 3) × (9 - 7)32:(4 + 7) × 3 - 933:((4 + 7) × 3) - 934:4 - 7 + 3 × 935:(4 - 7) + 3 × 936:4 - 7 +(3 × 9)37:(4 - 7) + (3 × 9)38:4 - (7 - 3 × 9)39:4 - (7 - (3 × 9))40:4 - 7 + 9 × 341:(4 - 7) + 9 × 342:4 - 7 +(9 × 3)43:(4 - 7) + (9 × 3)44:4 - (7 - 9 × 3)45:4 - (7 - (9 × 3))46:4 + 9 × 3 - 747:(4 + 9 × 3) - 748:(4 + (9 × 3)) - 749:4 + (9 × 3) - 750:4 + (9 × 3 - 7)51:4 + ((9 × 3) - 7)52:(4 × (9 - 7)) × 353:4 × (9 - 7) × 354:4 × ((9 - 7) × 3)55:(7 + 4) × 3 - 956:((7 + 4) × 3) - 957:(7 - 4) × 9 - 358:((7 - 4) × 9) - 359:9 × 3 + 4 - 760:(9 × 3) + 4 - 761:(9 × 3 + 4) - 762:((9 × 3) + 4) - 763:9 × 3 +(4 - 7)64:(9 × 3) + (4 - 7)65:9 × 3 - 7 + 466:(9 × 3) - 7 + 467:(9 × 3 - 7) + 468:((9 × 3) - 7) + 469:9 × 3 -(7 - 4)70:(9 × 3) - (7 - 4)71:(9 - 7) × 3 × 472:((9 - 7) × 3) × 473:(9 - 7) × (3 × 4)74:(9 - 7) × 4 × 375:((9 - 7) × 4) × 376:(9 - 7) × (4 × 3)77:(9 × (7 - 4)) - 378:9 × (7 - 4) - 3共两种:(3*4)*(9-7)
