\[\textbf{а)}\ 2^{\log_{2}(3 - 2x)} < 4\]
\[3 - 2x > 0\]
\[2x < 3\]
\[x < 1,5.\]
\[M = ( - \infty;1,5).\]
\[3 - 2x < 4\]
\[- 2x < 1\]
\[x > - 0,5.\]
\[Решение\ неравенства:\]
\[x \in ( - 0,5;1,5).\]
\[Ответ:\ x \in ( - 0,5;1,5).\]
\[\textbf{б)}\ 3^{\log_{3}(7 - 4x)} > 27\]
\[7 - 4x > 0\]
\[- 4x > - 7\]
\[x < \frac{7}{4}\]
\[x < 1,75.\]
\[M = ( - \infty;1,75).\]
\[7 - 4x > 27\]
\[- 4x > 20\]
\[x < - 5.\]
\[Решение\ неравенства:\]
\[x \in ( - \infty;\ - 5).\]
\[Ответ:\ x \in ( - \infty;\ - 5).\]
