Question

2. Suppose that for matrices A and B,

Answer 1

#2 in the attached file, hard to type out, sorry.

Answer 2

Find the transpose of A first, then multiply by B, then take the inverse of that matrix.

Answer 3

Oh, you are given A and B in terms of their inverses... interesting.

Answer 4

I know there is a theorem that has this property, but I can't remember it right now.
You might have to find A and B first from their inverses, and then do the operation.
That's a pain, though, I know. Try researching matrix properties here: http://tutorial.math.lamar.edu/Classes/LinAlg/InverseMatrices.aspx
