the inverse of a matrix can be created by a gauss-jordan appoach. consider row operations than turn the first matrix into the second. the inverse is the second part of the second matrix.
Find the inverse of matrix A, listed below, using this technique.
verify that you have the inverse by using the property that AA to the power of -1=1
