sqrt(19-4sqrt(x))=sqrt(12)-sqrt(7)

Which is the greatest among (sqrt(19)-sqrt(17)),(sqrt(13)-sqrt(11)),(sqrt(7)-sqrt(5)) and (sqrt(5)-sqrt(3))?

Which is the greatest among (sqrt(19)-sqrt(17)),(sqrt(13)-sqrt(11)),(sqrt(7)-sqrt(5)) and (sqrt(5)-sqrt(3))?

If x=sqrt(11)-sqrt(10),y=sqrt(12)-sqrt(11), then

4sqrt(3)-7sqrt(12)+2sqrt(75)=

Compare the surds (i) A=sqrt(10)-sqrt(5),B=sqrt(19)-sqrt(14) (ii) P=sqrt(10)+sqrt(5),Q=sqrt(8)+sqrt(7)

Compare the surds (i) A=sqrt(10)-sqrt(5),B=sqrt(19)-sqrt(14) (ii) P=sqrt(10)+sqrt(5),Q=sqrt(8)+sqrt(7)

given x=(sqrt(7)+sqrt(3))/(sqrt(7)-sqrt(3)),y=(sqrt(7)-sqrt(3))/(sqrt(7)+sqrt(3)) find the value of x^(4)+y^(4)+(x+y)^(4)

If sqrt(x)-sqrt(12)=sqrt(4)-sqrt(x) , then find x .

(1) sqrt(13-x sqrt(10))=sqrt(8)+sqrt(5) then find the value of x,(2) find sqrt(7+4sqrt(3))
