Question

5·5·5·1，这四个数，用加减乘除包括括号，怎样算出等于24

有点难

Answer 1

1除以5=0.2, 5-0.2=4.8, 5乘4.8=24

Answer 2

1: 5 × (5 - 1 ÷ 5)
2: 5 × (5 - (1 ÷ 5))
3: (5 - 1 ÷ 5) × 5
4: (5 - (1 ÷ 5)) × 5

Answer 3

5*(5-1/5)=24
5*(5-(1/5))=24
5*(5-1/5)=24
5*(5-(1/5))=24
(5-1/5)*5=24
(5-(1/5))*5=24
(5-1/5)*5=24
(5-(1/5))*5=24
5*(5-1/5)=24
5*(5-(1/5))=24
5*(5-1/5)=24
5*(5-(1/5))=24
(5-1/5)*5=24
(5-(1/5))*5=24
(5-1/5)*5=24
(5-(1/5))*5=24
5*(5-1/5)=24
5*(5-(1/5))=24
5*(5-1/5)=24
5*(5-(1/5))=24
(5-1/5)*5=24
(5-(1/5))*5=24
(5-1/5)*5=24
(5-(1/5))*5=24

Answer 4

5*(5-1/5)=24
5*(5-(1/5))=24

(5-1/5)*5=24
(5-(1/5))*5=24
5*(5-1/5)=24
5*(5-(1/5))=24
5*(5-1/5)=24
5*(5-(1/5))=24
(5-1/5)*5=24
(5-(1/5))*5=24
(5-1/5)*5=24
(5-(1/5))*5=24
5*(5-1/5)=24
5*(5-(1/5))=24
5*(5-1/5)=24
5*(5-(1/5))=24
(5-1/5)*5=24
(5-(1/5))*5=24
(5-1/5)*5=24
(5-(1/5))*5=24 5 × (5 - 1 ÷ 5)
2: 5 × (5 - (1 ÷ 5))
3: (5 - 1 ÷ 5) × 5
4: (5 - (1 ÷ 5)) × 5

Answer 5

(5*5)-1^5=24
