" If "x=9+4sqrt(5)," then "sqrt(x)-(1)/(sqrt(x))=?

if x=9+4sqrt(5) find the value of sqrt(x)-(1)/(sqrt(x))

Using properties of proportion, solve for x : (i) (sqrt(x + 5) + sqrt(x - 16))/ (sqrt(x + 5) - sqrt(x - 16)) = (7)/(3) (ii) (sqrt(x + 1) + sqrt(x - 1))/ (sqrt(x + 1) - sqrt(x - 1)) = (4x -1)/(2) . (iii) (3x + sqrt(9x^(2) -5))/(3x - sqrt(9x^(2) -5)) = 5 .

sqrt(x+1)-sqrt(x-1)=sqrt(4x-1)

Solve : sqrt(9+2x)-sqrt(2x)=(5)/(sqrt(9+2x)) .

Find x if (sqrt(5x) + sqrt(3x + 1))/(sqrt(5x) -sqrt(3x + 1)) = 9 .

If x= (4sqrt(15))/(sqrt5+sqrt3) , then (x+sqrt(20))/(x-sqrt(20))+(x+sqrt(12))/(x-sqrt(12))= ?

Solve: (2)/(sqrt(x))-(3)/(sqrt(y))=2 and (4)/(sqrt(x))-(9)/(sqrt(y))=-1

(2)/(sqrt(x))+(3)/(sqrt(y))=2 and (4)/(sqrt(x))-(9)/(sqrt(y))=-1

{:((2)/(sqrt(x))+ (3)/(sqrt(y)) = 2),((4)/(sqrt(x))-(9)/(sqrt(y)) = -1):}

sqrt(2)x^(2)+9x+4sqrt(2)
