1. Let G=GL(2,Q), Q meaning rational numbers, and let A =matrix 0 -1
and B =matrix 0 1
Show that A^4 = I = B^6, but that (AB)^n does not equal I for all n >0. Conclude that AB can have infinite order even though both factors A and B have finite order( this cannot happen in a finite group)
Define W=[(1 2)(3 4)], the cyclic subgroup of symmetric group with n=4 (S sub 4) generated by (1 2)(3 4). show that W is a normal subgroup of V but that W is not a normal subgroup of S sub 4. Conclude that normality is not transitive: K is a normal subgroup of H and H is a normal subgroup of G need not imply K is a subgroup of G.
V= four group
I really dont know how to do these, I need to learn them in written proof form and I struggle.© BrainMass Inc. brainmass.com October 25, 2018, 12:00 am ad1c9bdddf
This provides an example of a proof regarding a matrix with infinite order, and a proof regarding normal subgroups.

Can you help me complete this chart? We can use any 2 products from the same company. Thanks
1. Is the Boston Consulting Group (BCG) matrix reliable? Why/why not?
2. Given the shared template of BCG, choose any 2 products from the same company ( the below are examples only) and place them in the applicable quadrants of your choice. Explain the finding based on the applicable quadrant.
