If `a=2+sqrt(3)` then `a^(3)+1/(a^3)=`

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

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

If x=(2+sqrt(3))^((1)/(3)) then x^(3)+(1)/(x^(3))=

If i=sqrt(-)1, then 4+5(-(1)/(2)+(i sqrt(3))/(2))^(334)+3(-(1)/(2)+(i sqrt(3))/(2))^(365) is equal to (1)1-i sqrt(3)(2)-1+i sqrt(3)(3)i sqrt(3)(4)-i sqrt(3)

If i=sqrt(-1), then 4+5(-(1)/(2)+i(sqrt(3))/(2))^(334)+3(-(1)/(2)+i(sqrt(3))/(2))^(335) is equal to-

A line makes 30^(@) angle with positive direction of y axis in clockwise direction, then slope of line is : ( 1 ) sqrt(3) ( 2 ) - sqrt(3) ( 3 ) 1/(sqrt3) ( 4 ) - 1/(sqrt3)

Let C be the circle with centre at (1, 1) and radius = 1. If T is the circle centred at (0, y), passing through origin and touching the circle C externally, then the radius of T is equal to (1) (sqrt(3))/(sqrt(2)) (2) (sqrt(3))/2 (3) 1/2 (3) 1/4
