Question: problem3 row operations as matrix multiplication h let b ...

Question details

Problem3 Row operations as matrix multiplication. H) Let B = LA where A E R4x4 and 4 Points 1 0 0 0 o 10 1,2R. 0 -82 0 1 L-10-11 101 Show: B is the matrix which we get if in the matrix A we subtract from the third row the l1-multiple of the second row and from the fourth row &-multiple of the second row. What happens if we multiply L and A in reverse order? Hint: Compute C - AL and interpret the result as column operations
