WebTo do that, we multiply both sides by -1 like so:-1{(-a-b)/2}< -1{(ab)^1/2} and that gives us (a+b)/2 > -(ab)^1/2 where a,b are positive integers . now we all know that if a,b>0, there would not be any negative sign in of the the square root of (ab). so we put a modulus sign in front of the negative suare root of (ab) like so: (a+b)/2 > -(ab ...
