If x = 19 and y = 18, then the value of   is

If    then the value of a³ + b³ is 

Out of the given responses, one of the factors of (a² – b² )3 + (b² – c²) 3 + (c² – a²) 3 is

If x = y = 333 and z = 334, then the value of x³ + y³ + z³ – 3xyz is

If a = 34, b = c = 33, then the value of a³ + b³ + c³ – 3abc is

If a + b = 1 and a³ + b³ + 3ab = k, then the value of k is

If a + b + c = 6, a² + b² + c² = 14 and a³ + b³ + c³ = 36, then the value of abc is

If , then the value of x is
