![### Linear Algebra Exercises
#### Problem 1
Let \( U \) and \( V \) be two subspaces of \( \mathbb{R}^n \) such that \( U \subseteq V \). Show that \( \dim(U) \leq \dim(V) \).
#### Problem 2
Find a basis for the Null space of the matrix \( A \) of order \( 2 \times 5 \) given by:
\[
A = \begin{bmatrix}
2 & -2 & 1 & 0 & 4 \\
1 & 2 & -2 & -1 & 4
\end{bmatrix}
\]
#### Problem 3
Find a subset \( T \) of \( S = \{ \mathbf{v}_1, \mathbf{v}_2, \mathbf{v}_3, \mathbf{v}_4 \} \) such that \( T \) is a basis for \( \text{Span}(S) \).
\[
\mathbf{v}_1 = \begin{bmatrix} 3 \\ 7 \\ 1 \end{bmatrix}, \quad
\mathbf{v}_2 = \begin{bmatrix} 2 \\ 5 \\ 0 \end{bmatrix}, \quad
\mathbf{v}_3 = \begin{bmatrix} 1 \\ 2 \\ 1 \end{bmatrix}, \quad
\mathbf{v}_4 = \begin{bmatrix} 1 \\ 1 \\ 3 \end{bmatrix}
\]
