" 11."(x)/(sqrt(x+4))

If x=(11)/(4-sqrt(5)), find the value of x^(2)-8x+11

If f(x)=(1)/(sqrt(x+2 sqrt(2 x-4)))+(1)/(sqrt(x-2 sqrt(2 x-4))) , for x gt 2 , then f(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))

if cos^(-1)((2)/(3x))+cos^(-1)((3)/(4x))=(pi)/2, x>3/4 then x= (a) (sqrt(145))/(11) (b) (sqrt(145))/(12) (c) (sqrt(146))/(10) (d) (sqrt(146))/(11)

if cos^(-1)((2)/(3x))+cos^(-1)((3)/(4x))=(pi)/2, x>3/4 then x= (a) (sqrt(145))/(11) (b) (sqrt(145))/(12) (c) (sqrt(146))/(10) (d) (sqrt(146))/(11)
