`x=(2-sqrt(3))/(2+sqrt(3)),` find the value of `x+1/x`

If x=2+\ sqrt(3), find the value of x+1/x

If x = (sqrt(3) + sqrt(2))/(sqrt(3) - sqrt(2)) , find the value of x^(2) + (1)/(x^(2)) .

If x = (sqrt(5) + sqrt(3))/(sqrt(5) - sqrt(3)) , find the value of x^(3) + (1)/(x^(3)) .

If x=2+sqrt(3), find the value of x+(1)/(x)

If x = sqrt(3)- sqrt(2) find the value of x+(1)/(x)

(i) If x = (6ab)/(a + b) , find the value of : (x + 3a)/(x - 3a) + (x + 3b)/(x - 3b) . (ii) a = (4sqrt(6))/(sqrt(2) + sqrt(3)) , find the value of : (a + 2sqrt(2))/(a - 2sqrt(2)) + (a + 2sqrt(3))/(a - 2sqrt(3)) .

x=(4)/(2sqrt(3)+3sqrt(2)) then find the value of (x + (1)/(x))

If x = sqrt(3)- sqrt(2) find the value of x^(3)+ (1)/(x^(3))

If x=1-sqrt(2), find the value of (x-1/x)^3

If x = sqrt(3)- sqrt(2) find the value of x^(2)+ (1)/(x^(2))
