Question

Answer the following question:

Evaluate `|(2, 3, 5),(400, 600, 1000),(48, 47, 18)|` by using properties

Answer 1

Let D = `|(2, 3, 5),(400, 600, 1000),(48, 47, 18)|`

Taking 200 common from R₂, we get

D = `200|(2, 3, 5),(2, 3, 5),(48, 47, 18)|`

= 200(0)   …[∵ R₁ and R₂ are identical]

= 0
