Answer 1

Olá!

$A) \left[\begin{array}{ccc}2&4\\0&1\\\end{array}\right] + \left[\begin{array}{ccc}4&1\\7&0\end{array}\right] \\= \left[\begin{array}{ccc}2+4 &4-1\\0+7&1+0\\\end{array}\right]\\\\\left[\begin{array}{ccc}6&5\\7&1\\\end{array}\right]$

$B) \left[\begin{array}{ccc}2&4\\0&1\\\end{array}\right] + \left[\begin{array}{ccc}3&0\\5&-2\\\end{array}\right]\\\left[\begin{array}{ccc}2+3&4+0\\0+5&1+(-2)\\\end{array}\right]\\\\=\left[\begin{array}{ccc}5&4\\5&-1\\\end{array}\right]$

$C) \left[\begin{array}{ccc}4&1\\7&0\\\end{array}\right] + \left[\begin{array}{ccc}3&0\\5&-2\\\end{array}\right]\\=\left[\begin{array}{ccc}4+3&1+0\\7+5&0+(-2)\\\end{array}\right]\\= \left[\begin{array}{ccc}7&1\\12&-2\\\end{array}\right]$

$D) \left[\begin{array}{ccc}2&4\\0&1\\\end{array}\right] + \left[\begin{array}{ccc}4&1\\7&0\\\end{array}\right] + \left[\begin{array}{ccc}3&0\\5&-2\\\end{array}\right]\\= \left[\begin{array}{ccc}2+4+3&4+1+0\\0+7+5&1+0+(-2)\\\end{array}\right]\\\left[\begin{array}{ccc}9&5\\12&-1\\\end{array}\right]$
