Document Summary

Answer: b: given that det a = 15, det b = 5, det c = 3, the value of det(abc 1) is (a) 15 (b) 225 (c) 25 (d) 1/25 (e) cannot be determined from the information. Answer: c: given that det a = 4 and det b = 5, then the value of det(a + b) is (a) 9 (b) 20 (c) 4/5 (d) 5/4 (e) cannot be determined from the information. Answer: e. there is no theorem for det(a + b), only for det(ab): given that det a = 3 and det b = 5, then the value of det(a + b) is. 1 (a) 8 (b) 15 (c) 3/5 (d) 5/3 (e) cannot be determined from the information. Answer: b: given that det a = 3 and det b = 5, then the value of det(ab) is (a) 2 (b) -15 (c) -3/5 (d) -5/3 (e) cannot be determined from the information.
