    How Does Invertibility Affect the Determinant in Matrix Operations?

    is this correct? det(BAB^-1)= det(B)det(A)det(B^-1)= det(BB^-1)det(A)= det(I)det(A)= det(A) det(I) = 1

    How Does Invertibility Affect the Determinant in Matrix Operations?

    I suppose you can expand by det(B)det(A)det(B^-1) but I don't know how det(B) relates to det(B^-1). What I was thinking was by expanding and somehow getting B and B^-1 to = I somehow det(A) would remain

    How Does Invertibility Affect the Determinant in Matrix Operations?

    Homework Statement Let A and B be square matrices, with B invertible. Show that det(BAB^-1) = det(A) Homework Equations I think its based off the theorem: If A and B are nxn matrices, then det(AB)= det(A)det(B) The Attempt at a Solution I started by simplifying BAB^-1det(A)...
