Giải các phương trình :
$\begin{array}{l}
1)\,\,{4^x} + {11^x} + {\sqrt {32} ^x} = {13^x}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(1)\\
2)\,\,{9.2^{2x}} = 8\sqrt {{3^{2x + 1}}} \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(2)
\end{array}$

Giải các phương trình :
$\begin{array}{l}
1)\,{3.2^{\sqrt{x}-1}} - {8.2^{\frac{{\sqrt {x} - 1}}{2} }}+4 = 0\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(1)\\
2)\,\,{81^x} - {16^x} - 2\left( {{9^x} - {4^x}} \right) + {36^x} = 0\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(2)
\end{array}$
