5. Consider A= 10 7 8 7 7 5 6 5 8 6 10 9 7 5 9 10 The inverse matrix A' = 25 -41 10 -6 -41 68 -17 10 10 -17 5 -3 -6 10 -3 2 a) 5 pts) Find the row-sum norms of A, A' b) 5 pts) Find the condition number based on the row sum norms. 6. Apply Gauss-Seidel method to solve the following equations 21-4||X2 8 -3 -21% a) (7 pts) Rearrange the equations to achieve diagonal dominance. b) (6 pts) Start with an initial guess of x=[0, 0, 0], perform two iterations to obtain approximate iterative values of [x, X2, X3]
