I Solution. Since G is a nonempty subset of the group GL(3; Q) of invertible 3£3 matrices with entries in Qunder matrix multiplication, it is only necessary to check … WebI is the identity matrix. Thus every matrix in our set has an inverse. (4) Associativity: We have this because matrix multiplication is associative in general. iv) The set of matrices …
