Here are two possibilities to get the precision you want:

1. Use exact input:

  In:  N[(5/2)^125, 30]

 Out: 5.52714787526044456024726519219*10^49

2. Use a more precise input:

  In:  2.500000000000000000000000000000^125]

 Out:  5.527147875260444560247265192*10^49

There's probably a more elegant way to do this, but being pretty new at Mathematica myself, those were the only things I could think of.
