`sqrt(1+sqrt(6+sqrt9))`

(A) 1 (C)3

(B)2 (D)4

The value of x=sqrt(2+sqrt(2+sqrt(2+...))) is (a) -1 (b) 1 (c) 2 (d) 3

If x=\ ^3sqrt(2+sqrt(3)) , then x^3+1/(x^3)= (a) 2 (b) 4 (c) 8 (d) 9

The value of sqrt(6+sqrt(6+sqrt(6+))) ..........is (a) 4 (b) 3 (c) -2 (d) 3.5

1/(sqrt3 + sqrt2) + 1/(sqrt3 -sqrt2)=

tan^(-1)sqrt(3)-cot^(-1)(-sqrt(3)) is equal to (A) pi (B) -pi/2 (C) 0 (D) 2sqrt(3)

If sum_(k = 1)^(oo) (1)/((k + 2)sqrt(k) + ksqrt(k + 2)) = (sqrt(a) + sqrt(b))/(sqrt(c)) , where a, b, c in N and a,b,c in [1, 15] , then a + b + c is equal to

If a=sqrt(3),b=1/2(sqrt(6)+sqrt(2))dot and c=2, then find /_A

(sqrt(-2))(sqrt(-3)) is equal to A. sqrt(6) B. -sqrt(6) C. isqrt(6) D. none of these

If (sqrt(3)-\ 1)/(sqrt(3)+\ 1)=a-b\ sqrt(3) , then (a) a=2,\ b=1 (b) a=2,\ b=-1 (c) a=-2,\ b=1 (d) a=b=1

Evaluate : (i)sqrt(3-2sqrt(2))" "(ii)sqrt(9+6sqrt(2))
