(11+sqrt(11))(11-sqrt(11))

Simplify (sqrt(13)-sqrt(11))/(sqrt(13)+sqrt(11)) + (sqrt(13)+sqrt(11))/(sqrt(13)-sqrt(11))

Slove (3-sqrt(11)) (3+ sqrt(11))

If cosA=3/4, then 32 sin\ A/2 sin\ (5A)/2= (A) sqrt(11) (B) -sqrt(11) (C) 11 (D) -11

On the ellipse 2x^(2)+3y^(2)=1 the points at which the tangent is parallel to 4x=3y+4 are ( i )((2)/(sqrt(11)),(1)/(sqrt(11))) or (-(2)/(sqrt(11)),-(1)/(sqrt(11))) (ii) (-(2)/(sqrt(11)),(1)/(sqrt(11))) or ((2)/(sqrt(11)),-(1)/(sqrt(11))) (iii) (-(2)/(5),-(1)/(5)) (iv) ((3)/(5),(2)/(5)) or (-(3)/(5),-(2)/(5))

Simplify the following expressions. (sqrt(11) -sqrt(7))(sqrt(11) + sqrt7)

If sqrt(17+ xsqrt(11)) = sqrt(11) + sqrt(6) , then value of x^(2) will be:

sqrt(?)-11=sqrt(1521)

(sqrt(10)+sqrt(11)+sqrt(12))xx(sqrt(10)+sqrt(11)-sqrt(12))xx(sqrt(10)-sqrt(11)+sqrt(12))xx(sqrt(10)-sqrt(11)-sqrt(12))

Simplify (sqrt(11)+sqrt(8))(sqrt(11)-2sqrt(2))
