(5)/(sqrt(19)-sqrt(14))

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)

(sqrt(5)-sqrt(5))/(sqrt(5)-sqrt(5))

(3)/(sqrt(19-2sqrt(88)))-(8)/(sqrt(14+2sqrt(33)))=

If a<=3cos x+5sin(x-(pi)/(6))<=b for all x then (a,b) is (a)(-sqrt(19),sqrt(19))(b)(-17,17)(-sqrt(21),sqrt(21))( b) noneo fthese

( simplify )/(sqrt(19-sqrt(360)))-(1)/(sqrt(21-sqrt(440)))+(2)/(sqrt(20+sqrt(396)))=

Simplify (1)/(sqrt(19)-sqrt(360))-(1)/(sqrt(20)+sqrt(396))= _______

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