Question

Row equivalence is an equivalence relation on the set rmn of mn matrices with entries from the field (set) r of real numbers. Proof

Answer 1

Answer:

Prove that if a matrix A is row equivalent to a matrix B, and B is row equivalent to a matrix C , then A is row equivalent to C. Linear Algebra

Answer 2

Answer:

in the set z of integers define mrn if mn is a multiple of 4. prove that r is an equivalence relation.
