Question

In the matrix $⎡ ⎢ ⎢ ⎣ \begin{matrix} 2 & 5 & 19 & - 7 35 & - 2 & \frac{5}{2} & 12, \sqrt{3} & 1 & - 5 & 17 \end{matrix} ⎤ ⎥ ⎥ ⎦$ ,write
(ii)The elements $a_{13}, a_{21}, a_{33}, a_{24}, a_{23} .$

Solution

Let $⎡ ⎢ ⎢ ⎣ \begin{matrix} 2 & 5 & 19 & - 7 35 & - 2 & \frac{5}{2} & 12 \sqrt{3} & 1 & - 5 & 17 \end{matrix} ⎤ ⎥ ⎥ ⎦ = ⎡ ⎢ ⎣ \begin{matrix} a_{11} & a_{12} & a_{13} & a_{14} a_{21} & a_{22} & a_{23} & a_{24} a_{31} & a_{32} & a_{33} & a_{34} \end{matrix} ⎤ ⎥ ⎦$
On comparing the corresponding elements, we get
$a_{13} = 19, a_{21} = 35; a_{33} = - 5; a_{24} = 12; a_{23} = \frac{5}{2} .$
