Question 109(ii)
Verify the property x×(y×z)=(x×y)×z of rational numbers by using
x=23,y=−37 and z=12
and what is the name of this property?
Given, x=23,y=−37 and z=12
Now,
LHS
=x×(y×z)=23×(−37×12)=23×(−314)=−214=−17
and
RHS.
=(x×y)×z=(23×−37)×12=−27×12=−17
∴LHS=RHS
Hence verified.
x×(y×z)=(x×y)×z
is the associative property.
