Пусть 0" alt="t = 3^{x}; \ t> 0" align="absmiddle" class="latex-formula">
Тогда 1) \ 3^{x} = 3; \ x = 1\\ 2) 3^{x} = \frac{1}{3}; \ x = -1\\ " alt="3t^{2} - 10t + 3 \leq 0\\ t_{1,2} = \frac{10 б\sqrt{100 - 4\cdot 3\cdot3}}{6} = \frac{10б8}{6}\\ t_{1} = 3; \ \ t_{2} = \frac{1}{3}\\ \\ => 1) \ 3^{x} = 3; \ x = 1\\ 2) 3^{x} = \frac{1}{3}; \ x = -1\\ " align="absmiddle" class="latex-formula">
Следовательно ОО:
Получаем систему:
