- In Exercises 31-38, find the inverse of the given elementary matrix. [100012001]arrow_forwardIn Exercises 20-23, solve the given matrix equation for X. Simplify your answers as much as possible. (In the words of Albert Einstein, Everything should be made as simple as possible, but not simpler.) Assume that all matrices are invertible. ABXA1B1=I+Aarrow_forwardUse elementary matrices to find the inverse of A=100010abc, c0.arrow_forward
- Which of the following operations can we perform for a matrix A of any dimension? (i) A+A (ii) 2A (iii) AAarrow_forwardDoes every 22 matrix have an inverse? Explain why or why not. Explain what condition is necessary for an inverse to exist.arrow_forwardIn Exercises 48-63, use the Gauss-Jordan method to find the inverse of the given matrix (if it exists).

- Can a matrix with zeros on the diagonal have an inverse? If so, find an example. If not, prove why not. For simplicity, assume a 22 matrix.arrow_forwardDoes matrix multiplication commute? That is, does AB=BA ? If so, prove why it does. If not, explain why it does not.arrow_forwardIn Exercises 48-63, use the Gauss-Jordan method to find the inverse of the given matrix (if it exists). 62. over ℤ3arrow_forward
