Prove the given condition — task. Maths TNSB Mentoring, Class 10.

Prove that \((A^T)^T\) \(=\) \(A\), if \(A\) \(=\) \(\begin{bmatrix}
3 & 2 & 3\\
4 & 8 & 8\\
6 & 2 & 3
\end{bmatrix}\).

\(A^T\) \(=\)

[\begin{array}{l} i & i & i \\ i & i & i \\ i & i & i \end{array}]

\((A^T)^T\) \(=\)

[\begin{array}{l} i & i & i \\ i & i & i \\ i & i & i \end{array}]

Thus, \((A^T)^T\) \(A\).
