Question

Помогите пожалуйста

Answer 1

A^T = $\left[\begin{array}{cc}m&0\\3&n\\m-n&2\end{array}\right]$

2^T = $\left[\begin{array}{cc}2m&0\\6&2n\\2(m-n)&4\end{array}\right]$

2^T - B = $\left[\begin{array}{cc}m&n\\9&2n-1\\2m-3n&3\end{array}\right]$

(2^T - B)C = $\left[\begin{array}{cc}2n-m^{2}&m(1+n)\\4n-9m-2&9+m(2n-1)\\3mn-2m^{2}+6&5m-3n\end{array}\right]$
