Question

Help me with this question plzzz!!!!!​

Answer 1

Step-by-step explanation:

$Given:\left[\begin{array}{ccc}4&1\\5&8\end{array}\right]$

$A' =\left[\begin{array}{ccc}4&5\\1&8\end{array}\right]$

$A + A'=\left[\begin{array}{ccc}4&1\\5&8\end{array}\right] + \left[\begin{array}{ccc}4&5\\1&8\end{array}\right] = \left[\begin{array}{ccc}8&6\\6&16\\\end{array}\right]$

$=>(A + A')' = \left[\begin{array}{ccc}8&6\\6&16\\\end{array}\right]$

Since,

(A + A')' = A + A'

Hence, A + A' is symmetric matrix.

Hope it helps!
