So, here the vector space of three-by-one matrices with zero in the last row requires two vectors to form a basis for that vector space so the dimension of that vector spaces is two. So, here, the dimension is two.Definition 12.3.1: Vector Space. Let V be any nonempty set of objects. Define on V an operation, called addition, for any two elements →x, →y ∈ V, and denote this operation by →x + →y. Let scalar multiplication be defined for a real number a ∈ R and any element →x ∈ V and denote this operation by a→x.But, of course, since the dimension of the subspace is $4$, it is the whole $\mathbb{R}^4$, so any basis of the space would do. These computations are surely easier than computing the determinant of a $4\times 4$ matrix.

A vector space can have several bases; however all the bases have the same number of elements, called the dimension of the vector space. This article deals mainly with finite-dimensional vector spaces.
