Given that x³ + y³ = 72 and xy = 6 with x > y. Then the value of (x – y) 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

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

$$x+{1\over x}=2$$ and x is real, then the value of $$x^{17}+{1\over x^{19}}$$ is

If (m + 1) = √n + 3, the value of   $${1\over 2}\left({m^3-6m^2+12m-8\over \sqrt { n}}-n \right)  \ $$ is

if $${{5x-7}\over 3}+2={{4x-3}\over 4}+4x$$, then the value of (8x+5) is

if 2x² – 7x + 5 =0, then what is the value of $$x^2+{25\over 4x^2}$$

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