- In Exercises 5-8, write B as a linear combination of the other matrices, if possible. B=[311011],A1=[101010] A2=[120010],A3=[111000]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 7-12,find an LU factorization of the given matrix [221404344]arrow_forward
- In Exercises 48-63, use the Gauss-Jordan method to find the inverse of the given matrix (if it exists). 63. over ℤ7arrow_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. XA2=A1arrow_forwardIn Exercises 23-28, let A=[102311201] and B=[230211164] Use the matrix-column representation of the product to write each column of AB as a linear combination of the columns of A.arrow_forward
