If A is the corresponding nxn matrix and B is its inverse, which of the following is B? A. ов. 1 1 0 0 0 0 ... ... 1 - 1 - 1 1 0 0 0 1 - 1 0 - 1 1 0 0 ... 1 - 1 0 0 -1 1 ... For j= 1,2,..,n, let a;, b;, and ej denote the jth columns of A, B, and I, respectively. Evaluate Ab;. Ab; = Rewrite without parentheses. Multiply. %3D Because the result from the previous step is equal to V it follows that AB = 1. O . . . O
