Question 5: Download the dataset from https://drive.google.com/drive/folders/1A2B3C4D5E6F7G8H910J containing the files "algebraic_structures.xlsx" and "field_properties.txt." Instructions: 1. In "algebraic_structures.xlsx," each matrix is labeled with a structure name, such as group, ring, or field. 2. The file "field_properties.txt" lists properties of certain matrices and scalar values associated with each matrix. Answer the following: a) For any matrix labeled as a "field" in "algebraic structures.xlsx," determine whether it forms a field under standard matrix operations. Check for the presence of additive and multiplicative inverses and justify each step. b) For each matrix that forms a group under addition, verify if it is an abelian group. Describe the properties that characterize an abelian group and explain if the matrix G₁ from the dataset satisfies these properties. c) Using any matrix from the dataset that forms a ring, prove whether it has an identity element under multiplication. Discuss the significance of an identity element in a ring and the conditions under which a ring is a division ring. Show all steps in your derivation.
