x + y = 4, xy = 2, y + z = 5, yz = 3, z + x = 6 and xz =4, then find the value of x 3 + y 3 + z 3 – 3xyz.
...The value of:
�...(a – 2) 2 + (b + 6) 2 + (c – 1) 2 = 0, then find the value of a + b – c.
If x + y + z = 7, x² + y² + z² = 85 and x³ + y³ + z³ = 842, then the value of √3 xyz is:
...- If x² - 2x + 1 = 0, then find the value of (x² + x⁻²)(x² + x⁻²).
For a =-4 and b = 5, value of a² – b² is:
What is the HCF of (x³ + 3x² - x - 3) and (x³ + 4x² + x - 6)?
47.98 × 4.16 + √325 × 12.91 + ? = 79.93 × 5.91
