Question

Consider the binary operation * on Q defined by x * y = 1 + 12x + xy, ∀ x,y ∈ R then 2 * 3 equals.

Answer 1

Answer:

The value of  2 * 3 equals to 31 .

Step-by-step explanation:

As given in  the question

x * y = 1 + 12x + xy  ,  ∀ x,y ∈ R

Now  find out the value of 2 * 3 .

Put x = 2 and y = 3 in  the binary operation .

Thus

2 * 3 = 1 + 12 × 2 + 2 × 3

         = 1 + 24 + 6

         = 31

Therefore the value of  2 * 3 equals to 31 .
