You should remember that if you need to multiply a matrix with a scalar, you need to multiply each element of the matrix with the scalar, such that:

`A = v*((a,b),(c,d)) => A = ((v*a,v*b),(v*c,v*d))`

Notice that v represents the scalar(number) and A represents the matrix.

You may prove the requested identity evaluating the inverse of the new matrix `v*A` .

You need to remember that you may evaluate the inverse of a matrix only if its determinant is not equal to zero.

Supposing that the...
