please show your steps and your work clearly thank you! 2. Find all the subgroups of D4. Which subgroups are normal? What are all the factor groups of D4 up to isomorphism? Find all the subgroups of the quaternion group, Q8. Which subgroups are 3.
answer fully 16. Up to isomorphism, the only infinite eyelic group is Z, under the usual addition. What are the subgroups of Z? Establish the isomorphism between Z and 22. Establish the isomorphism between Z and 3Z. In general, between Z and nz for n a positive integer. 17. According to the Fundamental Theorem of Finite Abelian Groups, up to isomorphism, a finite abelian group of order n is isomorphic to a direct product of cyclic groups of prime power...
Utilizing theorem 2.2, please answer proposition 2.1. 2.1 Structure of Finite Abelian Groups Theorem 2.2 (Structure Theorem for Finite Abelian Groups). 1. Let n = pap2...pl with the pi distinct primes and the li non-zero. Let G be an abelian group of order n. We have G is isomorphic to a product Gpi x Gpr ... Ger where for each i, Gp; is a abelian group of order po 2. Let H be a finite abelian p-group of order pm...
Please answer the parts 6 and 7. Thank you. 2. In this problem, we will prove the following result: If G is a group of order 35, then G is isomorphic to Zg We will proceed by contradiction, so throughout the following questions, assume that G is a group of order 35 that is not cyclic. Most of these questions can he solved independently I. Show that every element of G except the identity has order 5 or 7. Let...
ANSWER 1 & 2 please. Show work for my understanding and upvote. THANK YOU!! 1. Consider the subgroups H-〈(123)〉 and K-〈(12)(34)〉 of the alternating group A123), (12) (34)). Carry out the following steps for both of these subgroups. When writing a coset, list all of its elements. (a) Write A as a disjoint union of the subgroup's left cosets. (b) Write A4 as a disjoint union of the subgroup's right cosets. (c) Determine whether the subgroup is normal in A...

please write clearly on paper and show all steps and circle the correct answer. Thank you! Use implicit differentiation to the curve ex+2y = x + xy +5. Then find the slope of the curve at the point (-2,1).
please show step by step solution with a clear explanation! 2. Let G be a group of order 21. Use Lagrange's Theorem or its consequences discussed in class to solve the following problems: (a) List all the possible orders of subgroups of G. (Don't forget the trivial subgroups.) (b) Show that every proper subgroup of G is cyclic. (c) List all the possible orders of elements of G? (Don't forget the identity element.) (d) Assume that G is abelian, so...
