How should this fraction involving powers be solved 
$$\sqrt { 5 } \cdot { \left( \frac { 5 }{ 4 }  \right)  }^{ \frac { 1 }{ 2 }  }$$

All I know is that this can be written as
$\sqrt { 5 } \cdot { \left( \frac { 5 }{ { 2 }^{ 2 } }  \right)  }^{ \frac { 1 }{ 2 }  }$
Any Ideas?

$\sqrt { 5 } { \left( \frac { \sqrt5 }{ \sqrt4 }  \right)}=$${\left( \frac { \sqrt {5*5} }{ 2 }  \right)}$=${\left( \frac { \sqrt {25} }{ 2 }  \right)}$=$\frac 52$
