well it should be 1/2 only cant be 1/2 as for x tending to (a very large no.) ,,the expression gets negative,,clearly.. you can justify this as you may 4 = (2)^2 and send 4 under sqrt sign with  aside ..

Other doubt: why I can not consider power the numerator and denominator without equal the expression to some variable?
