Which of the following is not true for a square matrix \(A\) of order \(A\) |
The inverse of matrix \(A\), if it exists is unique If \(A\) is invertible then \(\left(A^{-1}\right)^{-1}=A\) If \(A\) is invertible then \(\left(A^{T}\right)^{-1}=\left(A^{-1}\right)^{T}\) If \(A\) is invertible then \(det\left(A\right)=0\) |
If \(A\) is invertible then \(det\left(A\right)=0\) |
If A is invertible, then A must be non-singular. ($A^{-1}$ exist) $⇒|A|≠0$ |
