Exponentiation of real numbers[edit]
There is no such operation unless a specific clause is made (e.g. to restrict to non-negatives bases, or to use a branch of the complex-valued analytic function for values). Please, do not break good, correct examples in the table. Incnis Mrsi (talk) 20:24, 11 March 2013 (UTC)

Bad English[edit]
I can not understand this statement: "This should not be confused with a unit; any element with a multiplicative inverse." Maybe the part after ';' should be deleted. Doru001 (talk) 16:24, 19 January 2018 (UTC)
- A unit is any element with a multiplicative inverse. I've reworded the sentence. It now reads:
- "This should not be confused with a unit, i.e. any element with a multiplicative inverse. Unity itself is necessarily a unit."
- Is that better? Paul August ☎ 17:13, 19 January 2018 (UTC)
