Answer 1

Answer:

What language have had you written...?

The multiplicative identity of whole numbers is 1. This means that any whole number multiplied by 1 will equal that same whole number.

The multiplicative identity of any integer a is a number b which when multiplied with a, leaves it unchanged, i.e. b is called as the multiplicative identity of any integer a if a× b = a. Now, when we multiply 1 with any of the integers a we get a × 1 = a = 1 × a So, 1 is the multiplicative identity for integers.

So if a = 1 then only it's possible
