\(\left(3x-2^4\right).7^3=2.7^4\)
\(\left(3x-2^4\right)=2.7^4\div7^3\)
\(3x-2^4=2.7\)
\(3x-2^4=14\)
\(3x=14+2^4\)
\(3x=30\)
`=>` \(x=30\div3\)
`=> x=10`

\(\left(3x-2^4\right).7^3=2.7^4\)
=> \(\left(3x-2^4\right)=2.7^4:7^3\)
=> \(\left(3x-2^4\right)=2.7^1\)
=> \(\left(3x-2^4\right)=14\)
=> \(3x=14+2^4\)
=> 3x = 14 + 16
3x = 30
x=30 : 3
x = 10
Vậy x = 10

/x-3/=7-(-2)
/x-3/=9
x=/9+3/
x=/12/
x=/12/
<=> x= 12; -12
( 3x-24)*73=2*74
(3x-16)*343=4802
3x-16=14
3x=14+16
3x=30
=> x = 10
x-[42+(-28)]=-8
x-14=8
x=8+14
x=22

\(\left(3x-2^4\right).7^3=2.7^4\)
\(\Rightarrow\left(3x-2^4\right)=2.7^4:7^3=14\)
\(\Rightarrow\)\(3x=14+16=30\)
\(\Rightarrow x=30:3=10\)
Hưng à! xin lỗi nha! tui mắc cười quá! Nguyễn Huy Hưng trả lời câu hỏi của Nguyễn Dũng (Ông hiểu rồi chứ!)

\(\left(3x-2^4\right).7^3=2.7^4\)
\(3x-2^4=2.7^4:7^3\)
\(3x-16=2.7\)
\(3x-16=14\)
\(3x=14+16\)
\(3x=30\)
\(x=30:3\)
\(x=10\)
Vậy: x = 10
Nhớ k cho mình nhé! Thank you!!!
3x-2^4 = 2.7^4 : 7^3 = 2.7 = 14
3x = 14 + 2^4 = 14 + 16 = 30
x = 30 : 3 = 10
k mk nha

3x-16=14
3x=14+16
3x=30
x=30:3
x=10
t ick cho mk nha bn
\(\left(3x-2^4\right).7^3=2.7^4\\ \Leftrightarrow3x-16=2.7^4:7^3\\ \Leftrightarrow3x=14+16\\ \Leftrightarrow3x=30\\ \Leftrightarrow x=10\)
Vậy...
\(\left(2x-2^4\right).7^3=2.7^4\)
\(\Leftrightarrow\left(2x-2^4\right)=2.7^4:7^3\)
\(\Leftrightarrow2x-2^4=2.7\)
\(\Leftrightarrow2x-16=14\)
\(\Leftrightarrow2x=30\)
\(\Leftrightarrow x=15\)
Vậy ..
