Thui mình giải đại nhennnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn
=(x+x+x)+(1/2+2/3+3/6)
=3x+(3/6+4/6+3/6)
=3x+15
Hết ùiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
Bye nhennnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn

Chúc bn hok tốt !!!
1, (-37)+14+26+37=[(-37)+37]+14+26=0+40=40
2, (-24)+6+10+24=[(-24)+24]+6+10=0+16=16
3 , 15+23+(-25)+(-23)=[15+(-25)]+[23+(-23)]=-10
4, 60+33+(-50)+(-33)= [60+(-50)]+[33+(-33)]=10
5, (-16)+(-209)+(-14)+209=[(-16)+(-14)]+[(-209)+209]=-30
6, (-12)+(-13)+36+(-11)=[(-12)+(-11)]+[(-13)+36]=(-23)+23=0
* = 1 ; 2 ; 3 ; 4 5 ; 6 ; 7 ; 8 ; 9 ; 0
b/ 120 - x : 4 = 34 : 311
120 - x : 4 = 37
120 - x : 4 = 2187
x : 4 = 120 - 2187
x : 4 = -2067
=> x = -8268
a) 3*2 có tận cùng là 2 nên chia hết cho 2
vậy * = 0;1;2 ... 9
b) 120 - x : 4 = \(3^4:3^{11}\)
120 - x : 4 = \(-\left(3^7\right)\)
x : 4 = 120 - \(\left[-\left(3^7\right)\right]\)
x : 4 = 2307
x = 2307 x 4
x = 9228
???? câu hỏi đâu
nói mà chẳng thấy bài toán đâu
