Write the identity element for the binary operation * defined on the set `R` of all real numbers by the rule `a*b=(3a b)/7` for all `a ,\ b in Rdot`

Explanation

To find the identity element for the binary operation \( * \) defined on the set of real numbers \( R \) by the rule \( a * b = \frac{3ab}{7} \), we need to determine a value \( e \) such that for any real number \( a \):

\[ a * e = a \]

and
