1. Explain why the set M = {e,f,g} together with binary operations on M is a defined table (picture) does not form a group? (I will sent a picture regarding to this question)
2. Let (G, ◦) be a group. Prove that in any row of the table for the group operation
◦ elements of G cannot be repeated. Does the same statement also apply to table columns?
3. In the vector space Z47 over Z7 you can find the basis of the subspace U ∩ V , where
U = span{(3,1,4,5)T, (2,2,1,6)T, (1,0,0,1)T}
and
V = span{(1,2,4,1)T, (2,6,6,3)T, (5,3,6,5)T}.

The a-s-s-e-s-s-m-e-n-t will be 5 calculation questions.
Please see the questions shown in the screenshot. I will send you all the info after being hired, eg PPTs, student access etc. Please send a publish in 12hrs -1 day time, day 2, and day 3 as well. + Will need to publish some questions to ask the teacher and revise base on feedback (Send bk ard in 1 day max)

1.We say that two matrices A and B are row-equivalent if one can be obtained from the other by a finite sequence of elementary row operation. Show that if A and B are row-equivalent matrices, then the homogeneous systems of linear equations Ax = 0 and Bx = 0 have exactly same solutions.
2. Suppose R and R’ are 2 × 3 row-reduced echelon matrices and that the systems RX = 0 and R’X = 0 have exactly the same solutions. Prove that R = R’
3. Suppose A is a 2 × 1 matrix and that B is a 1 × 2 matrix. Prove that C = AB is not invertible.
4. For each matrix use elementary row operations to discover whether it is invertible, and to find the inverse in case it is.
