Question

动动脑筋吧！
2 2 2 = 6
3 3 3 = 6
4 4 4 = 6
5 5 5 = 6
6 6 6 = 6
7 7 7 = 6

Answer 1

2+2+2 = 6
3 *3 -3 = 6
4 +4 -√4 = 6
5/5 +5 = 6
6+ 6- 6 = 6
7 -7/ 7 = 6
3√8+3√ 8 +3√8 = 6
(9+9)/ 3√9 = 6
注：/是除号，3√是三次根,√是根号

Answer 2

2+2+2=6，3X3-3=6，√4+√4+√4=6，5+5÷5=6，7-7÷7=6，3√8+3√8+3√8=6

Answer 3

2+2+2=6
3×3-3=6
4+4-√4=6
5+5÷5=6
6-6+6=6
7-7÷7=6
9-9÷√9=6

Answer 4

2+2+2=6
3*3-3=6
4!/4*floor(4)=6 (笑
5/5+5=6
6+6-6=6
7-7/7=6
(omega(8)+omega(8)+omega(8))!=6 (笑
(omega(9)+omega(9)+omega(9))!=6 (笑
