Questions: A=[9 2 6; -4 -5 -6] (A^T)^T=

Solution Steps

To solve this problem, we need to understand the properties of matrix transposition. The transpose of a transpose of a matrix returns the original matrix. Therefore, $(A^T)^T = A$.

The problem involves the matrix $A$ given by: $$A = \begin{bmatrix} 9 & 2 & 6 \\ -4 & -5 & -6 \end{bmatrix}$$

The property of matrix transposition states that the transpose of the transpose of a matrix returns the original matrix: $$(A^T)^T = A$$

Given the property, we verify that: $$(A^T)^T = \begin{bmatrix} 9 & 2 & 6 \\ -4 & -5 & -6 \end{bmatrix}$$
