3x - 23 = 32 + 114
=> 3x - 8 = 9 + 1
=> 3x - 8 = 10
=> 3x = 18
=> x = 6
vậy_
1)\(3x-2^3=3^2+1^{14}=9+1=10\)\(10\)
\(\Rightarrow3x-8=10\Rightarrow3x=10+8=18\)
\(\Rightarrow x=18:3=6\)
2)\(2^5x-3^3x=121-\frac{15}{15}\)
\(\Rightarrow x.\left(2^5-3^3\right)=121-1\)
\(\Rightarrow x.5=120\Rightarrow x=120:5=24\)
bạn Minh ơi 5 nha mk ghi lộn rồi
