But, S transpose=S because S=ABCD=D transpose × D . As, multiplication of a matrix with its transpose is always symmetric so, my previous statement was correct . S transpose = S³(as you have proved), so, S transpose= S = S³, so multiplying by S on both sides we get S²= S⁴, so both statements are correct should be the answer, please verify mam
