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....

show that it is a group by verifying:closure law, associativity, identity element and the inverse. Camp e Set of matrices of order 2 x 2 of real entries is a group under matrix addition. i.e. S={[a b] : a, b, c, d E R} is a group under addition defined by [ 2]+(203 ) Cho are the Verify closure and associativity yourself.
Please show that in any monoid (semigroup with neutral element e) if some element a has inverse a^-1, this inverse is unique. This means no element can have more than one inverse. [Hint: Start from writing the definition of the inverse for element a. Consider an element a which has two inverses (a1)^-1 and (a2)^-1. Then think about the value of (a1)^-1a(a2)^-1]. Comment: This is about any monoid which has inverses for some elements, but not necessarily for all elements....
