cot((pi)/(24))=sqrt(a)+sqrt(b)+sqrt(c)+sqrt(d) when a

If sqrt(a)=sqrt(b)+sqrt(c) and sqrt(a),sqrt(b)) and sqrt(c) are there surds,then

If sqrt(a)>sqrt(b)>sqrt(c)>sqrt(d) where a,b,c and d are consecutive natural numbers then which of the following is correct (1)sqrt(a)-sqrt(b)>sqrt(c)-sqrt(d)(2)sqrt(c)-sqrt(d)>sqrt(a)-sqrt(b)(3)sqrt(a)-sqrt(c)>sqrt(b)-sqrt(d)(4)sqrt(c)-sqrt(d)=sqrt(a)-sqrt(b)
