Question

Sendo A=
[2 3]
[1 4]

e B=
[ 3 -1]
[-2 4]

Calcule:

A) A+B
B) A^t + 8^t
C) (A+B) ^t

Answer 1

A+B = $\left[\begin{array}{ccc}5&2\\-1&8\end{array}\right]$

$A^{t} +B^{t} = \left[\begin{array}{ccc}5&-1\\2&8\end{array}\right]$

$A^{t} + B^{t} = \left[\begin{array}{ccc}5&-1\\2&8\end{array}\right]$
