ko chắc
tham kảo rồi k đúng cho mk nha
( 3x + 24 ) . 54 = 7 . 56
3x + 24 = 7 . 56 : 54
3x + 16 = 7 . 52
3x + 16 = 175
3x = 159
x = 53
Xtudy well
\(\left(3.x+2\right)^4.5^4=7.5^6\)
\(\left(3.x+2\right)^4=7.5^6:5^4\)
\(\left(3x+2\right)^4=7.5^2\)
\(3.x+2^4=175\)
\(3.x+16=175\)
\(3.x=175-16\)
\(3.x=159\)
\(x=159:3\)
\(x=53\)
Vậy \(x=53\)
Chúc bạn học tốt !!!
