You are given the following information about a new binary operator valid for a,b,c E R+, known as smiley-face: I. In order of operations, it takes precedence over Multiplicaiton/Divison. That is, the order of operations is now: P,E,Ⓒ,MD,AS II. aa = a III. aⒸ (boc) √(ab).c Note that THIS smiley-face operator is actuall self consistent. To wit: Using the definition: a (aa) √(aa).a √a·a Evaluating the parentheses first: a (aⒸa) = a Ⓒa = a That is to say: I BELIEVE it is self-consistent! Let me know if I've messed up again!!! = = = Here is the question. Solve for x ER: 2023 Ⓒ (170x) = 357 = √a² = a
None of the others. Suppose is a binary operation on a set S. Which statement best describes problem? Must have either an identity or a zero (if exists), but not both. Must only have at most one idempotent. An idempotent (if exists) must be either an identity or a zero. If it has an identity and a zero, then they must be the same element. LII
