If x, y, z are the three factors of a ³– 7a – 6, then value of x + y + z will be

Find the value of the given expression-

(4^x+4 -5× 4^x+2) / 15×4^x – 2²×4^x

Given that x = 80, y = -35 and z = -45, Determine the value of [(x³ + y³ + z³)/10³]

If 9x² + y² = 37 and xy=2, x, y>0, then the value of (27x³ + y³) is:

If x = (2+√3)/(2-√3), y = (2-√3)/(2+√3). Then find out the value of (x²+y²-xy)/(x²+y²+xy)?
