Answer 1

GIVEN :

Verify the identity property for addition and multiplication for the rational numbers  and  

TO FIND :

The identity property for addition and multiplication for the rational numbers  and  is true

SOLUTION :

Given that the rational numbers are  and  

Now we can verify the identity property for addition and multiplication for the rational numbers

Identity property for addition for the rational numbers :

For any real number 'a' we have

i) a+o=a

For the numbers  and  

Now put a= we get

Now put a=

⇒ Identity property for addition for the given rational numbers is true and is verified.

Identity property for multiplication for the rational numbers :

For any real number 'a' we have

i)  

For the numbers  and  

Now put a= we get

Now put a=

⇒ Identity property for multiplication for the given rational numbers is true and is verified.
