If `x = sqrt(3)` then find `( x + sqrt(3) ) ( x - sqrt3 )`

If x=3-sqrt(5) Then find the value of (sqrt(x))/(sqrt(2)+sqrt(3x-2))

Evaluate : ( sqrt(2)x + sqrt(3)y ) ( sqrt(2)x + sqrt(3)y )

Find x if (sqrt(3x +1) + sqrt(3x - 6))/(sqrt(3x + 1) - sqrt(3x - 6)) = 7

Complete the following activity to solve the quadratic equation sqrt(3) x^(2) +4x- 7 sqrt(3) = 0 by factorisation method : sqrt(3) x^(2) +4x- 7 sqrt(3) = 0 :. sqrt(3) x^(2) + square - 3x - 7 sqrt(3) = 0 :. x( sqrt(3) x + ) - sqrt(3) ( sqrt(3) x + 7) = 0 :. (" ") (x-sqrt(3))= 0 :. sqrt(3) x + 7 = 0 or square = 0 :. x = ( -7)/( sqrt(3)) or x = square :. (-7)/(sqrt(3)) and sqrt(3) are the roots of the equation.

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

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

If x=3sqrt(a)+(1)/(3sqrt(a)) then find x^(3)-3x
