Commutativity and Associativity Check

📺 Watch Video Explanation:


Check commutativity and associativity

Given:

\( a * b = a^b, \quad a,b \in \mathbb{N} \)

Commutativity:

\( a * b = a^b \)
\( b * a = b^a \)

Example:

\( 2^3 = 8 \neq 3^2 = 9 \)

❌ Operation is NOT commutative

Associativity:

LHS:

\( (a*b)*c = (a^b)^c = a^{bc} \)

RHS:

\( a*(b*c) = a^{(b^c)} \)

Example:

\( (2^3)^2 = 8^2 = 64 \)
\( 2^{(3^2)} = 2^9 = 512 \)

❌ Operation is NOT associative

Conclusion:

❌ Neither commutative nor associative
