Solution Writing the above statement in symbolic form, we have
p ⇒ q, where, p is “matrix A is invertible” and q is “A is non singular”
Instead of proving the given statement, we prove its contrapositive statement, i e ,
if A is not a non singular matrix, then the matrix A is not invertible Rationalised 2023-24
