- In Exercises 47-52, assume that A and B are nn matrices with det A = 3 and det B=2. Find the indicated determinants. det (AAT)arrow_forwardIn Exercises 20-23, solve the given matrix equation for X. Simplify your answers as much as possible. (In the words of Albert Einstein, Everything should be made as simple as possible, but not simpler.) Assume that all matrices are invertible. ABXA1B1=I+Aarrow_forwardIn Exercises30-35, verify Theorem 3.32 by finding the matrix of ST (a) by direct substitution and (b) by matrix multiplication of [S] [T].
