What is the simplified form the expression (1+x)(1+x²)(1+x⁴)(1+x⁸)(1-x)?

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

If x = 332, y = 333, z = 335, then the value of x³ + y³ + z³ – 3xyz is

Directions: In each of these questions, two equations (i) and (ii) are given, you have to solve both the equations and give answer accordingly.

(i) 2x² + 9x + 9 = 0
 (ii) 15y² + 16y + 4 = 0

Directions: In each of these questions, two equations (i) and (ii) are given, you have to solve both the equations and give answer accordingly.

(i) 2x³ = $$ \sqrt {256}$$
 (ii) 2y² – 9y + 10 = 0
