+3sqrt%285%29%2Fsqrt%289%29+

To get rid of the radical on the bottom multiply by:
+sqrt%289%29%2Fsqrt%289%29+
to get:
.
+%283sqrt%285%29%2Fsqrt%289%29%29+%28sqrt%289%29%2Fsqrt%289%29%29+
+%283sqrt%285%29sqrt%289%29%29%2F9+
+%28sqrt%285%29sqrt%289%29%29%2F3+
+%28sqrt%2845%29%29%2F3+
+%28sqrt%283%2A3%2A5%29%29%2F3+
