Explicação passo-a-passo:

\left(\begin{array}{cccc}a_{11} &a_{12} &a_{13} &a_{14} \\a_{21} &a_{22} &a_{23} &a_{24} \a&a_{31} &a_{32} &a_{33}&a_{34} {}  \\a_{41} &a _{42} &a_{43} &a_{44} \end{array}\right)=\\\\a_{11}=4.1-3.1=4-3=1\\\\a12=4.1-3.2=4-6=-2\\\\a13=4.1-3.3=4-9=-5\\\\a14 = 4.1-3.4=4-12=-8\\\\a21=4.2-3.1=8-3=5\\\\a22=4.2-3.2=8-6=2\\\\a23=4.2-3.3=8-9=-1\\\\a24=4.2-3.4=8-12=-4\\\\a31=4.3-3.1=12-3=9\\\\a32==4.3-3.2=12-6=6\\\\a33=4.3-3.3 = 12-9=3\\\\a34=4.3-3.4=12-12=0\\\\a41=4.4-3.1=16-3=13\\\\a42=4.4-3.2=16-6=10\\\\a43=4.3-3.3=12-9=3\\\\a44=4.4-3.4=16-12=4

Na matri[tex][/tex]z inicial substitua esses valores.

\left(\begin{array}{cccc}a_{11} &a_{12} &a_{13} &a_{14} \\a_{21} &a_{22} &a_{23} &a_{24} \a&a_{31} &a_{32} &a_{33}&a_{34} {}  \\a_{41} &a _{42} &a_{43} &a_{44} \end{array}\right)
