laplace of sqrt(1+2*sqrt(t)+3/sqrt(t))
code:
syms t
f =sqrt(3/sqrt(t)+1+2*sqrt(t));
laplace(f)
oputput:
ans =
laplace((3/t^(1/2) + 2*t^(1/2) + 1)^(1/2), t, s)
its not solving it why??

Why do you assume an analytical Laplace transform exists? There are many functions for which this is not true. Even then, there are some functions for which you may need to transform the problem for a symbolic tool to work. I would point out that Wolfram Alpha also fails to solve this problem as posed.
