I suspect the question is 'what is +2%2F%283-sqrt%285%29%29+ ?'
If so, +2%2F%283-sqrt%285%29%29+

= +%282%2A%283%2Bsqrt%285%29%29%29+%2F+%28%283-sqrt%285%29%29%2A%283%2Bsqrt%285%29%29%29+

= +%286%2B2sqrt%285%29%29+%2F+%289-5%29+

= +highlight%28+%283%2Bsqrt%285%29%29+%2F+2%29+ (approximately 2.618034)

If the question is really 'what is +2%2F3+-+sqrt%285%29+?' — as the question is written — then there is no simplification, and the value is approximately -1.569401. Be sure to use parenthesis.
