Question

if AB matrix=matrix(-1 3 0 2) and B^-1=matrix (1 2 3 4) then find A matrix

Answer 1

Please answer to my question

Answer 2

If \(AB=C\), then \(A=C*B^{-1}\)

Answer 3

so multiply the matrices

Answer 4

matrix(-1 3 0 2)*matrix(1 2 3 4)

Answer 5

will u please explain with the detailed explanationn

Answer 6

doing that on here would take me a very long time... as you see it is not easy to show a matrix. I dont even know what you mean by matric{1 2 3 4} is this a 2 by 2 matrix or a 1 by 4 matrix... all you need to do is learn how to multiply matrices.
