1. The problem statement, all variables and given/known data Let A and B be n x m matrices, and λ and μ be real numbers. Prove that: [itex](λA+μB)^T = λA^T+μB^t[/itex] 2. Relevant equations :/ 3. The attempt at a solution I'm struggling to start here. If there was no λ and μ, I think I'd be able to reasonably solve this. How do I show that these real numbers don't matter in this exchange?
