Let A and B denote n x n invertible matrices: a. Show that A^-1 + B^-1 = A^-1(A + B)B^-1. b. If A + B is also invertible, show that A^-1 + B^-1 is invertible and find a formula for (A^-1 + B^-1)^-1.

If the inverse of $A^{2}$ is $B$, show that the inverse of $A$ is $A B$. (Thus $A$ is invertible whenever $A^{2}$ is invertible.)
