Hint: Here we use basic concept of determinant of matrix

Given: A is skew –symmetric matrix

Solution:

\rightarrow \text { Let } \mathrm{A} \text { is } 3 \times 3 \text { skew-symmetric matrix }

So, \mathrm{A}=\left[\begin{array}{ccc} 0 & a_{12} & a_{13} \\ a_{21} & 0 & a_{23} \\ a_{31} & a_{32} & 0 \end{array}\right]

\rightarrowHere all diagonal entries are zero

\rightarrow So, we know that it’s determinant zero
