\[1)\ \left( 2^{\frac{1}{\sqrt{2}}} \right)^{\sqrt{8}} = 2^{\left( \frac{1}{\sqrt{2}} \bullet \sqrt{8} \right)} = 2^{\sqrt{4}} =\]
\[= 2^{2} = 4;\]
\[2)\ \left( 2^{\sqrt{27}} \right)^{\sqrt{3}} \bullet 2^{- 3} =\]
\[= 2^{\left( \sqrt{27} \bullet \sqrt{3} \right)} \bullet 2^{- 3} = 2^{\sqrt{81} - 3} =\]
\[= 2^{9 - 3} = 2^{6} = 64.\]
