If p – 2q = 4, then the value of p³ – 8q³ – 24pq – 64 is :

The value of $$5-{8+2\sqrt{15} \over4}-{{1}\over8+2\sqrt{15}}$$ is equal to:

$$ {4\over 7}×{2{4\over 5}} ÷{2\over 5}=?$$

The value of $${0.7×0.7×0.7+0.3×0.3×0.3}\over {0.7×0.7-0.7×0.3+0.3×0.3}$$ is

if $${x\over 9}+{8\over x}=1$$, then the value of x³ is :

If p = 99, then value of p(p² + 3p + 3) is

If m + n = 1, then what will be the value of m³ + n³ + 3mn?
