(a) |AB| = |A| |B| = -1 * 2 = -2.
<span>(b) |B^5| = |B|^5 = 2^5 = 32. </span>
<span>(c) Since A is 4 x 4, </span>
<span>|2A| = 2^4 * |A| = 16 * -1 = -16. </span>
<span>(d) Since determinants are invariant under transposition, </span>
<span>|A^t A| = |A^t| |A| = |A| |A| = (-1)(-1) = 1. </span>
<span>(e) |B^(-1) AB| = |B^(-1)| |A| |B| </span>
<span>.....................= (1/|B|) |A| |B| </span>
<span>.....................= |A| </span>
<span>.....................= -1. </span>
