(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

2. Relevant equations

Reduce the matrix to reduced matrix by removing 1 row completely

Number of trees = determinant of [ Ar times Ar^{T}]

3. The attempt at a solution

I removed 4th row to get Ar(reduced matrix)

Then I did Ar times Ar (transpose)

And found it's determinant but I got different answer depending on which row I remove.

Do I randomly remove any row?

Sorry for posting too many homework questions. I have an exam coming up in Feb.
