If x³ + y³ = 35 and xy = 6, x > y, then value of (x − y) will be

If x^3 – y^3 = 117/8 and x – y = 3/2 then the value of x^2 + xy + y^2 will be

If x + (1/y) = 1 and y + (1/z) = 1, then the value of z + (1/x) is

If x + 1/x = 2, then the value of (2x² + 2)/(3x² + 4x + 3) will be:

If 2ˣ × 3ʸ = 12 and 2ʸ × 3ˣ = 18, then the value of x + y is :

If x + 1/x = k and x² + 1/x² = k, then values of k are
