Question

on set N a*b=a+2b then 2*(3*4)

Answer 1

Given:

a*b = a+2b

To find:

The value of 2*(3*4)

Calculation:

Assume a=3, b=4 and substitute the values according to the given relation

  2*(3*4) = 2*(3+2(4))

              = 2*(3+8)

              = 2*(11)

              = 2*11

Now, Let a=2, b=11 and substitute the values according to the given relation

  2*11 = 2+2(11)

         = 2+22

         = 24

Final answer:

The value of 2*(3*4) is 24
