Beweisen Sie das Lemma.&lt;br /&gt;

==Aufgabe 7.2==&lt;br /&gt;
Bestimmen Sie eine Basis des von der Menge erzeugenten Vektorraum U=&amp;lt;X&amp;gt;.&amp;lt;br /&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
X=\{\begin{pmatrix} 0 \\ 1 \\0 \\-1 \end{pmatrix};\begin{pmatrix} 1 \\ 0 \\ 1\\-2 \end{pmatrix}; \begin{pmatrix} -1 \\ -2 \\ 0\\1 \end{pmatrix}; \begin{pmatrix} -1 \\ 0 \\ 1\\0 \end{pmatrix}; \begin{pmatrix} 1 \\ 0 \\ -1\\-1 \end{pmatrix}; \begin{pmatrix} 2 \\ 0 \\ -1\\0 \end{pmatrix}\}.&amp;lt;/math&amp;gt;&amp;lt;br /&amp;gt;&lt;br /&gt;

v_1 = (1,-2,0,1)\,,\;\, v_2 = (0,0,2,5)\,, \;\, v_3 = (-2,4,2,3)&amp;lt;/math&amp;gt;&lt;br /&gt;

a) Prüfen Sie, ob die Vektoren &amp;lt;math&amp;gt;v_1 = (4,4,4),\; v_2 = (2,4,6)&amp;lt;/math&amp;gt; und &amp;lt;math&amp;gt;v_3 = (3,4,5)&amp;lt;/math&amp;gt; ein Erzeugendensystem von&amp;lt;math&amp;gt; {\mathbb R}^3&amp;lt;/math&amp;gt; bilden.&amp;lt;br /&amp;gt;&lt;br /&gt;
b) Untersuchen Sie, für welche &amp;lt;math&amp;gt;t \in {\mathbb R}&amp;lt;/math&amp;gt; die Vektoren &amp;lt;math&amp;gt;v_1 = (1,3,4)\,, \;\, v_2 = (3,t,11)\,, \;\, v_3 = (-4,-4,0)&amp;lt;/math&amp;gt; linear abhängig in &amp;lt;math&amp;gt;{\mathbb R}^3&amp;lt;/math&amp;gt; sind.&lt;br /&gt;
