Question

Помогите пожалуйста

Answer 1

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

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

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

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