\(10-\left\{\left[\left(x:3+17\right):10+3.2^4\right]:10\right\}=5\)
\(\Leftrightarrow\left[\left(x:3+17\right):10+3.2^4\right]:10=5\)
\(\Leftrightarrow\left(x:3+17\right):10+3.16=50\)
\(\Leftrightarrow\left(x:3+17\right):10+48=50\)
\(\Leftrightarrow\left(x:3+17\right):10=2\)
\(\Leftrightarrow x:3+17=20\Leftrightarrow x:3=3\)
\(\Leftrightarrow x=9\)
mk làm gọn bn làm chi tiết hơn nha
