add everything with a similar base (radical)
13√11 - 6√11 + 5√7 + 4√7
7√11 + 9√7
thats as much as it simplifies.

Just group your like terms.
13 â11 +5 â7 - 6 â11 + 4 â7
= (13-6)â11 + (5+4)â7
= 7â11+ 9â7

How far does the simplification need to go? If not all that far, just combine the two square roots of 11 (+13 and -6) to get 7 square root of 11. Then do the same for the two square roots of 7 to get 9 square root of 7.
Where do you get the little square root symbol? My keyboard does not have it.
