12:{390[500-(125+35:7)}]
mấy bạn giải lại giùm mình nha
12:{390:[500-(125 +35 .7)]}. giải giúp e vỚI ạ e đag cần gấp ạ
12 : {390 : [500 - (125 + 35 . 7)]}
= 12 : {390 : [500 - (125 + 245)]}
= 12 : [390 : (500 - 370)]
= 12 : (390 : 130)
= 12 : 3
= 4
12 : { 390 : [ 500 - ( 125 + 35. 7 ) ] }
= 12 : { 390 : [ 500 - ( 125 + 245 ) ] }
= 12 : { 390 : [ 500 - 370 ] }
= 12 : { 390 : 130 }
= 12 : 3
= 4
12 :{390 :[500 - (125 + 35 . 7)]}
= 12 : {390 : [500 - (125 + 245)]}
= 12 : [390 : (500 - 370)]
= 12 : (390 : 130)
= 12 : 3
= 4
12 : { 390 : [ 500 - ( 125 + 35 . 7 ) ] }
Số cần tìm là:

\(12:\left\{390:\left[500-\left(125+35.7\right)\right]\right\}\)
\(=12:\left\{390:\left[500-370\right]\right\}\)

Hok tốt
a) 28 . 64 + 28 . 36 b) 12: {390 : [500 - (125 + 35 . 7)]}
Giải gấp!!!
a)100:{2.[22-(35-8)]}
b)12:{390:[500-(125+35.7)]}
\(100:\left\{2\cdot\left[22-\left(35-8\right)\right]\right\}\\ =100:\left\{2\cdot\left[22-27\right]\right\}\\ =100:\left(-10\right)\\ =-10\)
\(12:\left\{390:\left[500-\left(125+35\cdot7\right)\right]\right\}\\ =12:\left\{390:\left[500-370\right]\right\}\\ =12:3\\ =4\)
a) 100:{ 2.[22-(35-8)]}
=100:{2.[22-27]}
=100:{2.(-5)}
=100: 10
