Question

Let ∗ be the binary operation on N given by a∗b= LCM of a and b. (i) Find 5∗7,20∗16.

Answer 1

Answer:

It is given that the binary operation on N given by a ∗ b =

It is given that the binary operation on N given by a ∗ b = L.C.M. of a and b.

Then,

5 * 7 = LCM of 5 and 7 = 35

5 * 7 = LCM of 5 and 7 = 3520 * 16 = LCM of 20 and 16 = 80.
