If x = a(b - c), y = b(c – a) and z = c(a - b) , find the value of (x/a)3 + (y/b)3 + (z/c)3?
+ If a = (√2 - 1)1/3, then the value of (a-1/a)3 +3(a-1/a) is:
Solve for x in the equation: 3(x + 2) + 2(2x - 5) = 5x + 9
If (x - 1) 3 + (y - 2) 3 + (z - 3) 3 + 3(x + y - 3)(y + z - 5)(x + z - 4) = 0, then what is the value of (x + y +...
