Find the rank of the matrix 2 2 4 4 4 8 .. Answer . Recall that the rank of a matrix 𝐴 is equal to the number of rows/columns of the largest square submatrix of 𝐴 that has a nonzero determinant.. Since the matrix is a 2 × 2 square matrix, the largest possible square submatrix is the original matrix itself. Its rank must therefore be …

WebSolve the system of equations using Cramer’s Rule: { 3 x + y − 6 z = −3 2 x + 6 y + 3 z = 0 3 x + 2 y − 3 z = −6. Cramer’s rule does not work when the value of the D determinant is 0, as this would mean we would be dividing by 0. But when D = 0, the system is either inconsistent or dependent.

It characterizes some properties of the matrix and the linear map represented by the matrix. In particular, the determinant is nonzero if and only if the matrix is invertible and the linear map represented by the matrix is an isomorphism.
