Transpose of a matrix is obtained by interchanging the rows and the columns of matrix A. It is denoted by A’.

e.g. A12 = A21

A = $\begin{bmatrix} 2 &-3 & 5 \\[0.3em] 0& 7 & -4\\[0.3em] \end{bmatrix}$

Hence transpose of matrix A is,

A' = $\begin{bmatrix} 2 &0 \\[0.3em] -3& 7 \\[0.3em] 5&-4 \end{bmatrix}$

(A')' = A

Hence, Proved.
