a) Mệnh đề \(P \Rightarrow Q\) là: “Nếu \({a^2} < {b^2}\) thì  \(0 < a < b\)”

b) Mệnh đề \(Q \Rightarrow P\) là: “Nếu \(0 < a < b\) thì \({a^2} < {b^2}\)”

c) Mệnh đề \(P \Rightarrow Q\) là: “Nếu \({a^2} < {b^2}\) thì  \(0 < a < b\)” sai,

Chẳng hạn \(a =  2;\;b = -3\) ta có: \({2^2} < {( - 3)^2}\) nhưng không suy ra \(0<2<-3\).

 Mệnh đề \(Q \Rightarrow P\) là: “Nếu \(0 < a < b\) thì \({a^2} < {b^2}\)” đúng.
