Let a*b=6a^4-9b^4 be a binary operation on R, then * is commutative.(a

1.	Let ab=6a^4-9b^4 be a binary operation on R, then is commutative.(a) True(b) FalseI have been asked this question in an online interview.I want to ask this question from Binary Operations in section Relations and Functions of Mathematics – Class 12
Answer» Correct option is (b) False The BEST explanation: The GIVEN statement is false. The BINARY operation ‘’ is commutative if ab=ba Here, ab=6a^4-9b^4 and ba=6b^4-9a^4 ⇒ab≠ba Hence, the ‘’ is not commutative.
