You cannot.


The sum of square roots does not have any particular algebraic rule to apply.
The only possibility is to factorize the numbers and collect the common factors, but in this case the three numbers in the square roots are primes, so cannot be factorized.
The conclusion is that you cannot simplify this expression more than its original format.
