Question

Algebra lesson identity
a and b only

Answer 1

Answer:

Step-by-step explanation:

In algebra a and b is identity if and only if

a*b= b*a= I

Where l is one because in multiplication the identity is one

So if we multiplaye a and b the answer is one.

In other words a is multiplicative inverse of b .

For example if a= 3 and b=1/3 then a is multiplicative inverse of b because the answer is one
