Exercise 1.1
1. Name the property under multiplication used in each of the following.
Solution:
Property used: – a x 1= 1 x a = a
1 is the multiplicative identity
Solution:
Property used: – Commutativity – (a x b = b x a)
Solution:
Property used: – Multiplicative Inverse – (a x = 1)
2. Tell what property allows you to compute
Solution:
Here Associative property is used to compute the given expression
As, a x (b x c) = (a x b) x c
3. The product of two rational numbers is always a
Solution: Rational number
