Linear algebra matrix inversion

(A/2)^T =
1 -2
-1 1

the 2x2 matrix is to the power of -1, (I don't know how to type that sorry)

how would you go about doing this?

Note that 1/2 is just a number, when you distribute the tranpose, nothing really happens to it.

So really you have

½Aᵗ

[1 -2]
[-1 1]

If you don't know, the tranpose of a matrix tranposed is itself, i.e.

(Aᵗ)ᵗ = A

[1 -1]
[-2 1]

Multiply every element by 2 to A

[2 -2]
[-4 2]
