Which of the following is false ?
Options
- AAddition is commutative in
- BMultiplication is associative in
- CIf a * b=a^ b for all a, b N then * is commutative in
- DAddition is associative in N
Correct answer
C. If a * b=a^ b for all a, b N then * is commutative in
Step-by-step solution
Since, for the set of natural numbers with respect to addition, it is commutative and associative. Also, for the set of natural numbers with respect to multiplication, it is associative. Hence, option (c) is false.
