If A is 3x3 with all entries 1's and 0's, what is the max value of det(A)?
I answered it to be 1, which is wrong. Can someone help me?
Thanks!
Use Laplace's formula on the first row and you'll get
since each entry can only be either 1 or 0, just try to find the coefficients such that you are always summing and not subtracting. You will find that the answer to your question is 2.
