Question

24 : { 390 - [ 500 - ( 125 + 35 . 7 ) ] } = 2\(^x\)

Answer 1

\(24:\left\{390-[500-\left(125+35.7\right)]\right\}=2^x\)

\(24:\left\{390-[500-\left(125+245\right)]\right\}=2^x\)

\(24:\left\{390-[500-370]\right\}=2^x\)

\(24:\left\{390-130\right\}=2^x\)

\(24:260=2^x\)

Chỗ này sai đề ạ !

Answer 2

24 : { 390 - [ 500 - ( 125 + 35 . 7 ) ] } = 2^x

2^x = 24 : { 390 - [ 500 - ( 125 + 245 ) ] }

2^x = 24 : { 390 - [ 500 - 370 ] }

2^x = 24 : { 390 - 130 }

2^x = 24 : 260

2^x = 6/65 = ......................

=> Đề sai
