You can put this solution on YOUR website! M[10,5:6,12]
These are both valid notations for the determinant of a matrix.
detM[10,5:6,12]=M[D,10,5:6,12]
The determinant of a 2x2 matrix can be found using the formula M[D,a,b:c,d]=ad-cb
detM[10,5:6,12]=(10)(12)-(6)(5)
Simplify the determinant.
detM[10,5:6,12]=90
The determinant of M[10,5:6,12] is 90.
90
The determinant of matrix A is given by
det(A) = a*d - c*b
