Let Ao be an 5 x 5-matrix with det(Ao) = 2. Compute the determinant of the matrices A1, A2, A3, A4 and As, obtained from Ao by the following operations: A₁ is obtained from Ao by multiplying the fourth row of Ao by the number 3. det(A₁)= [2mark] Az is obtained from Ao by replacing the second row by the sum of itself plus the 4 times the third row. det(A₂)= [2mark] A3 is obtained from Ao by multiplying Ao by itself... det(A3) = [2mark] A4 is obtained from Ao by swapping the first and last rows of Ao- det(A4) = [2mark] As is obtained from Ao by scaling Ao by the number 3. det(As) = [2 mark]
