It is well known that for invertible matrices 𝐴,𝐵 𝐴 , 𝐵 of the same size we have (𝐴𝐵 ) −1 = 𝐵 −1 𝐴 −1 ( 𝐴 𝐵 ) − 1 = 𝐵 − 1 𝐴 − 1 and a nice way for me to remember this is the following sentence: The opposite of putting on socks and shoes is taking the shoes off, followed by taking the socks off. Now, a similar law holds for the transpose, namely: (𝐴𝐵 ) 𝑇 = 𝐵 𝑇 𝐴 𝑇 ( 𝐴 𝐵 ) 𝑇 = 𝐵 𝑇 𝐴 𝑇 for matrices 𝐴,𝐵 𝐴 , 𝐵 such that the product 𝐴𝐵 𝐴 𝐵
