A 55⋅(45) 2 B … Web6 jan. 2024 · Statement 2 gives us x^3*y^3< (xy)^2. Since (xy)^2 is always positive, we can divide the inequality by (xy)^2 without changing the sign. Hence, (xy)<1. However, we still don't know their exact value. If xy<0, then one of the variables is positive and the other negative and this would be sufficient.
