If a^2 b^2 c^2=14, then ab BC ca is always greater than or equal to...
A² + b² + c² = 14
In this situation we are aware of the fact that the square of every number is greater than or equal to 0.
now we will take the square of (a+b+c)
=} (a+b+c)²≥ 0
=} a² + b² + c² + 2(ab + bc + ca) ≥ 0
=} 14 +2 (ab + bc + ca) ≥ 0
=} 2 (ab + bc + ca) ≥ - 14
=} ab + bc + ca ≥ -14/2
=} ab + bc + ca ≥ - 7
