How do you do this?

That is the answer just not sure how you do that process.

I'm just not getting it.. Probably missing the obvious..

So I do SQRT(49/4 + 196/4) now what?

I think I see it now, the 49/4 and 196/4 is just 245/4 and divide the 245 by 49 makes 5. So now I have SQRT(5 * 49/4) so I can simplify the 49/4 and leave the 5 as it is to make 7/2 SQRT(5).
