A, B are two matrixes in size mxn, kxm respectively. Which of the claims are right? If the claim is right, prove it. If the claim isn't right, bring a counter exa. if the first two rows of A are equal, then t first two rows of BA are equal too. 6) if the first two columns of A are equalit the first two columns of BA are equal too. d if there is no Zeroes in the main diagonal then there is no Zeroes in the main diagona BA too.

A, B are two matrixes in size mxn, kxm respectively. Which of the claims are right? If the claim is right, prove it. If the claim isn't right, bring a counter example. a if the first two rows of A are equal, then the first two rows of BA are equal too. b) if the first two columns of A are equal, then the first two columns of BA are equal too. c) if there is no Zeroes in the main diagonal of A₂ then there is no Zeroes in the main diagonal BA too. of KRE
