Homework Statement
Let A = BC
where B is 8*3 and C is 3*8
Prove that A is singular.
Homework Equations
A is singular when Det(A)=0
The Attempt at a Solution
When B and C are multiplied the result is A which is an 8*8 matrix. However, top prove it can't be non singular i chose a smaller matrix (2*3) and (3*2) and the result showed that if i chose the same numbers the answer is 0. But how do i prove it without numbers?
