Answer 1

@Christininja

Answer 2

No Calculators allowed!!!

Answer 3

try ggogling

Answer 4

How big is the matrix? What are its dimensions?

Answer 5

The reason I ask is that there's a quick way for 2x2 matrices. Higher order \(n\times n\) matrices require a bit of work.

Answer 6

it is \[\left[\begin{matrix}3 & 8\\ 2 & 4\end{matrix}\right]\]
so \[2 \times 2\]
(we have the same problem)
