3 square roots of 54 minus 2 square roots of 24 minus 1 square root of 96 plus 4 square roots of 63.
Assume it is:
3sqrt%2854%29+-+2sqrt%2824%29+-+sqrt%2896%29+%2B+4sqrt%2863%29
See what we can factor inside the radical, to reveal some perfect squares:
3sqrt%289%2A6%29+-+2sqrt%284%2A6%29+-+sqrt%2816%2A6%29+%2B+4sqrt%289%2A7%29
Extract those square roots
3%2A3sqrt%286%29+-+2%2A2sqrt%286%29+-+4sqrt%286%29+%2B+4%2A3sqrt%287%29
which is
9sqrt%286%29+-+4sqrt%286%29+-+4sqrt%286%29+%2B+12sqrt%287%29
Like terms, 9 - 4 - 4
sqrt%286%29%2B12sqrt%287%29, using a calc: = 34.1985
