Question

If A = `[(0, 2),(3, −4)]` and kA = `[(0, 3"a"),(2"b", 24)]`, then the values of k, a and b respectively are:

विकल्प

• −6, −12, −18

• −6, −4, −9

• −6, 4, 9

• −6, 12, 18

Answer 1

−6, −4, −9

Explanation:

kA = `[(0, 2"k"),(3"k", −4"k")] = [(0, 3"a"),(2"b", 24)]`

k = −6, a = −4 and b = −9
