Hi,
My question is if you have 2 matrices A and B, such that:
AB=24IHow can I prove that;
A−1=241B
Intuitively it makes sense, however my textbook doesn't provide a proof for this which I'm curious about so hopefully someone can explain.
Edit:
24I was just an example I chose. These equations can be generalised to
AB=xIThus
A−1=x1B
