<U>Notice how I edited your input using parentheses  3*sqrt(2x^2-10)  to make your formula readable . . . </U>


<pre>
1.  The number 3 together with its neighborhood lies in the domain of the given function.


2.  In addition, the function  {{{3*sqrt(2x^2-10)}}} is continuous at the poin x= 3.


3.  Therefore, you can simply substitute the value x= 3 into the function to get its limit as x approaches 3:


    lim  {{{3*sqrt(2x^2-10)}}} = {{{3*sqrt(2*3^2-10)}}} = {{{3*sqrt(2*9-10)}}} = {{{3*sqrt(8)}}} = {{{6*sqrt(2)}}}.
   x-->3

Solved.
