If   $$ a={b^2\over b-a} $$  then the value of a³ + b³ is 

If x = 2 then the value of x³ + 27x² + 243x + 631 is

If a + b – c = 0 then the value of 2b²c² + 2c²a² + 2a²b² –a⁴ – b⁴ – c⁴

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

The HCF of x⁸ – 1 and x⁴ + 2x³ – 2x – 1 is :

If x = – 1, then the value of   $$ {1\over x^{99}}+{1\over x^{98}}+{1\over x^{97}}+{1\over x^{96}}+{1\over x^{95}}+{1\over x^{94}}+x $$ is

If $${{p^2\over q^2}+{q^2\over p^2}}=1$$, then the value of (p⁶ + q⁶ ) is

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