Question 2. In this exercise, you will show that Z[V-5] is not a U.F.D. (but it is an I.D., as you proved last lecture!) You will learn a common trick for reasoning about irreducibility and primality in a ring - with the help of special multiplicative functions to Z>. (i) First, calculate the units in Z[V-5] [Hint: calculate inverses first, assuming you can divide ("work- ing in Q[V-5]", and then see which ones actually lie in Z[V-5]] (ii) Next, we...

Product of pseudo-inverses Suppose A and D are right-invertible
matrices and the prod-
uct AD exists. We have seen that if B is a right inverse of A
and E is a right inverse of D, then EB
is a right inverse of AD. Now suppose B is the pseudo-inverse of
A and E is the pseudo-inverse of
D. Is EB the pseudo-inverse of AD? Prove that this is always
true or give an example for which it
is false....

Complete all parts. Do not skip any portion of the question.
Identify which of the following are rings. List out of the
properties. For those that are not rings, explain why not. Assume
addition and mulitiplication unless stated otherwise.
For those that are rings, state the identity elements under both
operations. Note if the ring is noncommutative. List the units
(those with multiplicative inverses) of each ring.
