What is the condition of a matrix to have an inverse? Find the inverse of the matrix $A = \begin{bmatrix} 5 & 1 & 2 \ 1 & 0 & 3 \ 4 & -3 & 8 \end{bmatrix}$ [10]
$$A = \begin{bmatrix} 5 & 1 & 2 \ 1 & 0 & 3 \ 4 & -3 & 8 \end{bmatrix}$$ Required: (a) condition for existence of inverse, (b) find $A^{-1}$. A square matrix $A$ of order $n \times n$ has an inverse if and only if it is non-singular, that is: $$\det(A) \neq 0$$ If $\det(A) = 0$, $A$ is singular...
