The Limit does not exist.

Explanation:

Reqd Lim.=lim_(x to 3)(sqrt3x-3)/(sqrt(2x-4)-sqrt2).

=lim_(x to 3)(sqrt3x-3)/(sqrt(2x-4)-sqrt2)xx(sqrt(2x-4)+sqrt2)/(sqrt(2x-4)+sqrt2).

=lim_(x to 3) {(sqrt3x-3)(sqrt(2x-4)+sqrt2)}/{(2x-4)-2}

=lim_(x to 3){(sqrt3x-3)(sqrt(2x-4)+sqrt2)}/{2(x-3)}

So, as long as, (x-3) is there in the Dr., the limit does not exist.
