I have already answered this question. It was posted. Then, it disappeared into the stratosphere. That's strange.

 

In any case, usually, this expression would be in its simplified form already. However, in this case, the radicands (numbers inside of the radical) happen to be perfect squares, so this expression can be simplified further:

 

\(2\sqrt{4}+5\sqrt{9}\) \(\sqrt{4}=2\hspace{1mm}\text{and}\hspace{1mm}\sqrt{9}=3\)
\(2*2+5*3\) Now, it is a matter of simplifying from here.
\(4+15\)  
\(19\)
