Is R 2 Q 2 \mathbb{R}^2 \setminus \mathbb{Q}^2 Homeomorphic To R Q \mathbb{R} \setminus \mathbb{Q} ?

Let R 2 Q 2 \mathbb{R}^2 \setminus \mathbb{Q}^2 denote the Cartesian plane minus all points whose coordinates are both rational. Similarly, let R Q \mathbb{R} \setminus \mathbb{Q} denote the irrational numbers. Are the spaces R 2 Q 2 \mathbb{R}^2 \setminus \mathbb{Q}^2 and R Q \mathbb{R} \setminus \mathbb{Q} homeomorphic?


Hint : Is R 2 Q 2 \mathbb{R}^2 \setminus \mathbb{Q}^2 path-connected?
