Q:
Let \( V=\{(a, b) \mid a, b \in \mathbb{R}\} \), vector addition \( (+) \) and scalar multiplication \( (\cdot) \) be defined
as follows:
For any \( \alpha \in \mathbb{R} \) and \( \left(a_{1}, b_{1}\right),\left(a_{2}, b_{2}\right) \in V \)
1) \( \left(a_{1}, b_{1}\right)+\left(a_{2}, b_{2}\right)=\left(a_{1}+a_{2}, b_{1}+b_{2}\right) \)
2) \( \alpha \cdot\left(a_{1}, b_{1}\right)=\left(\alpha^{2} a_{1}, \alpha^{2} b_{1}\right) \)
Is \( (V, \mathbb{R},+, \cdot) \) a vector space? Explain your answer.
