1.4.14 Matrix Transformations

Condition: a) Is it true that if the work of matrices \ (c^{t} \ cdot p^{t} \) is determined, then the work of matrices \ (p \ cdot c \) is determined, to substantiate the answer. b) give an example of cubic matrices \ (a \) and \ (b \), for which \ (a \ cdot b \ neq b^{t} \ cdot a^{t} \).
