Answer 2

Answer:

1.--> 80

2.--> 9

Step-by-step explanation:

1.   IF A MATRIX HAS SIZE  n × n  AND c IS A CONSTANT THEN

    det(c A)=c^{n} det(A)

⇒  det(4A) = 4² * DET(A)

⇒               = 16*5

                  = 80

2.         det(3A) = k det(A)

⇒     3³ * det(A) = k * det(A)

⇒    9 = k

⇒     k = 9
