If x = 1/(√3 + 1), then value of 4x³ − 2x² − 8x + 5 is

If x + (1/x) = 3, then the value of x³ + (1/x³) is :

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

If (a² − 1)/a = 2, then the value of (a⁶ − 1)/a³ is:

If 2^(x−1) + 2^(x+1) = 1280, then the value of x²+9x is

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