Check which of the following are solution of the equation x-2y=4 and which are not : (sqrt(2),4sqrt2)

Evaluate 2[4(sqrt(3))^3.sqrt(2)+4(sqrt(2))(sqrt(3))^3]

Let the length of latus rectum of an ellipse with its major axis along x-axis and center at the origin,be 8. If the distance between the foci of this ellipse is equal to the length of the minor axis,then which of the following points lies on it: (a) (4sqrt(2),2sqrt(2)) (b) (4sqrt(3),2sqrt(2)) (c) (4sqrt(3),2sqrt(3))( d) (4sqrt(2),2sqrt(3))

4. . simplify (4+sqrt(2))(4-sqrt(2))

sin( 67 1/2)^(@) + cos( 67 1/2)^(@) is equal to A) 1/2sqrt(4+2sqrt(2)) , B) 1/2sqrt(4-2sqrt(2)) , C) 1/4(sqrt(4+2sqrt(2))) , D) 1/4(sqrt(4-2sqrt(2)))

sin(67 1/2)^(@) + cos( 67 1/2)^(@) is equal to A) 1/2sqrt(4+2sqrt(2)) , B) 1/2sqrt(4-2sqrt(2)) , C) 1/4(sqrt(4+2sqrt(2))) , D) 1/4(sqrt(4-2sqrt(2)))

The line y=x sqrt(2)+4 sqrt(2) is a normal to y^(2)=4 a x then a=

(sqrt(a)+sqrt(2))^(4)+(sqrt(a)-sqrt(2))^(4)

(sqrt(a)+sqrt(2))^(4)+(sqrt(a)-sqrt(2))^(4)

Evaluate : lim_(n to oo)[(sqrt(n))/((3+4sqrt(n))^(2))+(sqrt(n))/(sqrt(2)(3sqrt(2)+4sqrt(n))^(2))+(sqrt(n))/(sqrt(3)(3sqrt(3)+4sqrt(n))^(2))+.......+(1)/(49n)]
