True/False: Determine whether any TWO of the three following statements is true or false, and justify your answer. 1. If A is a 127 × 341 matrix, then Nul(A) is a subspace of R127. (ULA, Exercise 3.5.3a) 2. If the nullity of A is 0, then the columns of A are linearly independent. (ULA, Exercise 3.5.3b) 3. If A is an m x n matrix and Col(A) = R", then A is invertible. (ULA, Exercise 3.5.3c)
