%282%2F7%29sqrt%28147%29+-+%281%2F3%29sqrt%2827%29+-+sqrt%2848%29

OK... first we need to convert every sqrt number into some useful factors...so...

48 --> 12x4 --> 3x4x4 --> 3x16
27 --> 9x3
147 --> 49x3

so, %282%2F7%29sqrt%2849%2A3%29+-+%281%2F3%29sqrt%289%2A3%29+-+sqrt%2816%2A3%29

%282%2F7%297sqrt%283%29+-+%281%2F3%293sqrt%283%29+-+4sqrt%283%29
2sqrt%283%29+-+sqrt%283%29+-+4sqrt%283%29
-3sqrt%283%29
