Question

Логарифмиеское неравенство?

Answer 1

$log_{log_49}(x^2+14x+49)\leq 0\\x^2+14x+49>0\Leftrightarrow \Leftrightarrow (x+7)^2>0\Rightarrow x\neq -7\\\Leftrightarrow x^2+14x+49\leq log_4^09\Leftrightarrow (x+7)^2\leq 1\Leftrightarrow \\\Leftrightarrow (x+7-1)(x+7+1)\leq 0\Leftrightarrow \\\Leftrightarrow (x+6)(x+8)\leq 0\Rightarrow x\in [-8;-6];x\neq -7\\x\in [-8;-6]\setminus \begin{Bmatrix}-7\end{Bmatrix}$
