\[1)\ {2,4}^{3 - 2x} = {2,4}^{3x - 2}\]
\[3 - 2x = 3x - 2\]
\[- 5x = - 5\]
\[x = 1.\]
\[Ответ:\ \ 1.\]
\[2)\ \left( \frac{5}{3} \right)^{x} = \left( \frac{3}{5} \right)^{x - 2}\]
\[\left( \frac{3}{5} \right)^{- x} = \left( \frac{3}{5} \right)^{x - 2}\]
\[- x = x - 2\]
\[- 2x = - 2\]
\[x = 1.\]
\[Ответ:\ \ 1.\]
\[3)\ \frac{1}{\sqrt{8}} = \left( \frac{1}{16} \right)^{- x}\]
\[8^{- \frac{1}{2}} = 16^{- ( - x)}\]
\[\left( 2^{3} \right)^{- \frac{1}{2}} = \left( 2^{4} \right)^{x}\]
\[2^{- \frac{3}{2}} = 2^{4x}\]
\[- \frac{3}{2} = 4x\]
\[x = - \frac{3}{8}.\]
\[Ответ:\ - \frac{3}{8}.\]
