簡單!

5的平方根x5的平方根x5-1

=24!!!

拿計算機自己計啦!!!

(5-1/5)*5

=(5-0.2)*5

=4.8*5

=24


(5/1)+(5*5)-(5+1)

=5+25-6

=30-6

=24

如果只從加減乘除去想會覺得根本沒有答案,但若想到平方根這樣的運算符號的話,則可以想到。

(√5*5)*5-1

我只想到這個!!!!!!!!!!!!!!!!!

use factorial
Note: 5! = 5x4x3x2x1

[(5! - 5) / 5]+1
=> [(120-5)/5]+1
=> 115/5 +1
=> 23+1
=> 24

squareroot(5x5) x 5 - 1 = 24

breakdown :

squareroot(5x5) = 5,
5 x 5 = 25
25 - 1 = 24

係中間到加上運算符號點樣可以等於24

5 ×(5-1÷5) = 24

如果可以加0,上面的答案先合理
