What was the day on 15th august 1947?

If the sum of {a\over b}and its reciprocal is 1 and a ≠ 0, b ≠ 0, then the value of a³ + b³ is

If a = 2·361, b = 3·263 and c = 5·624, then the value of a³ + b³ – c³ + 3abc is

If p, q, r are all real numbers, then (p – q)³ + (q – r)³ + (r – p)³ is equal to 

If a³ – b³ – c³ – 3abc = 0, then 

If x = 2 - 2^1/3 + 2^2/3, then the value of x³– 6x² + 18x + 18 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

The value of (x + y + z)³ – (y + z – x)³ – (z + x – y)³ – (x + y – z)³ is:
