Is it ok to reduce the two matrices through row operations first before multiplying them together or will the answer no longer be row equivalent? Thanks for any input!

Homework Statement Let A be the matrix with eigenvalues x1 = 2, x2 = 1, x3 = 1/2 , x4 = 10 and corresponding eigenvectors v1: <1,-1,1,0>, v2: <1,-1,0,0>, v3: <1,0,0,1>, v4: <0,0,1,1> Calculate |A|Homework Equations See aboveThe Attempt at a Solution I'm not really sure how to start this...

If I reduce two matrices using row operations before multiplying them together, will I still get a row-equivalent answer to the result I would of gotten if I hadn't reduced them? Thanks for any input!
