How do you find the inverse of #A=##((3, 4, 6, 0, 5), (2, 0, 8, 0, 4), (2, 0, 1, 0, 1), (1, 4, 2, 0, 0), (0, 1, 3, 0, 4))#?

I do not think your matrix has an inverse:

Explanation:

Your matrix has an entire column of zeros. This implies that its determinant will be zero: the determinant must be different from zero to have an inverse!

The inverse will be the Adjoint of your original matrix divided by the value of the determinant! The division by zero, in this case, will make impossible for it to be evaluated.
