Substitute x = 1  t and expand the squareroots in series using the formula:
sqrt[1 + y] = 1 + y/2 + O(y^2)
You should then find that the limit is 1/2

or
Multiply by ((5X)^.5 + 2)/((5X)^.5 + 2)*((2X)^.5 + 1)/((2X)^.5 + 1)
which reduces your question to
Limit ((2X)^.5 + 1)/((5X)^.5 + 2) as x>1
= 2/4
= 1/2
BTW, it is strongly suggested that you do not put your email or personal information in these postings
