(7-5*(-13))/3=24
(7-(5*(-13)))/3=24
(7-(-13)*5)/3=24
(7-((-13)*5))/3=24
希望以上答案对楼主有所帮助，另祝楼主好运！

求采纳
4*(5+7)-24=24
(4*(5+7))-24=24
4*(7+5)-24=24
(4*(7+5))-24=24
(5+7)*4-24=24
((5+7)*4)-24=24
(7+5)*4-24=24
((7+5)*4)-24=24
解法如下；
（1）3×（5×2-2）=24
（2）（5×2-2）×3=24
科学型：
（5-2÷2）×3!=24（4!=24）

解：不是所有的四个数都是算出24的。这一组7、7、6、9不论是四则运算，还是幂运算，都不能得到结果为24.无解。
这个不好算，应该是负五吧
-5*（-13）+7再除以3
