**Unformatted text preview: **I , by Problem 23, I is row equivalent to B . So we have that A is row equivalent to I and I is row equivalent to B . By Part (a), we get that A is row equivalent to B . / ——————– A short version of Part (b) is like the following: Suppose both A and B are nonsinngular n × n matrices. By Theorem 1.4.2, A is row equivalent to I and B is row equivalent to I . By Problem 23, I is row equivalent to B . By Part (a), A is row equivalent to B . / 1...
