Question

28. Which pair of following numbers are respectively the additive & multiplicative identities
:) 2 &0
(ii) 1 & 1
(iv) 0 & 1
(iii) 1 & 0
f3/A+ -- 1/4) + (-- 5/4)​

Answer 1

Heyaa

The total of any number is always 0(zero) and which is always the original number. Zero is always called the identity element. whenever a number is multiplied by the number 1 (one) it will give the same number as the productthe multiplicative identity is 1 (the number one)

So additive identity is 0 and multiplicative identity is 1

Hope this will solve your doubt

Answer 2

Answer:

0 is the Additive identity for all numbers.

Therefore, ( 2&0), (0&1) are the additive identity.

Multiplicative identity is the number which when you multiply, the result remains same as the number. 1 is the multiplicative identity.

Hence, (1&1), (0&1), (1&0) are the multiplicative identities.

Thanking you.
