Let Ao be an 5 x 5-matrix with det(A) = 2. Compute the determinant of the matrices A1, A2, A3, A4 and A5, obtained from Ao by the following operations:
A₁ is obtained from Ao by multiplying the fourth row of An by the number 2.
det(A₁) = _____ [2mark]

A₂ is obtained from Ao by replacing the second row by the sum of itself plus the 2 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 Ag. det(A4) = _____ [2mark]

A5 is obtained from Ao by scaling Ao by the number 4.
det(A5) = ______ [2mark]
