`Hey,
Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.
a)
Det=4*(1/3)-2*(2/3)=0
It is a singular matrix
b)
Det=4*(-2)-(-3)*(6)=10
It is not a singular matrix
c)
Det=8*(2*3+4)+1*(4*3-4*3)+3*(4*1-(-3)*2)=110
It is not a singular matrix
Kindly revert for any queries
Thanks.
