4. Three matrices are defined as [A]=6125184[B]=[40.502][C]=[2321] a. Perform all possible multiplications that can be computed between pairs of these matrices. b. Justify why the remaining pairs cannot be multiplied. 5. Given the system of equations 32+73=41+223=05122=3 a. Compute the determinant. b. Use Cramer's rule to solve for the x.s. c. Use Gauss elimination with partial pivoting to solve for the x 's. As part of the computation, calculate the determinant in order to verify the value computed in (a). d. Substitute your results back into the original equations to check your solution. 6. Apply gauss Jordan method to solve the system of equations: x+y+2z=43x+y3z=42x3y5z=5 7. Consider the system of equation of the form AX=B, where A=421132212 X=xyz and B=737. Find by using Gauss-jordan method. a. A1 b. The numerical solution of the given system
