Expanded and removed prod tag[edit]

I've expanded the article, improved its formatting, added links to OEIS and MathWorld, and recategorised it. I think it now deserves to be kept, so I've removed the prod tag. One further comment - the prod tag comment said there are no articles on second powers or third powers - in fact, there are; they are called square number and cube (arithmetic).

This is certainly an improvement; but compare to Square number or even cube (arithmetic). Is there notable content here? Maybe the reference to Waring's problem, but that's in that article. Septentrionalis PMAnderson 03:04, 9 January 2007 (UTC)[reply]

I have always thought there was some flexibility with the number articles; so long as the powers don't expand beyond 4, it doesn't seem worse to me (personally) if they stop at 4 rather than 3. When I put the prod, I didn't realize there were articles for 2 and 3. CMummert 03:36, 9 January 2007 (UTC)[reply]

Multiply how many times?[edit]

If I multiply n by itself once, I get n squared; if I multiply n by itself twice, I get n cubed...

I've changed the article to lessen confusion (I hope)

More vocabulary please[edit]

I’m not a native English-speaker, and neither have I been to an English-speaking school, yet I’m interested in knowing how to actually say, like teachers and pupils do, things like :

would a teacher instruct "put N to the fourth power" or "take N’s fourth power" or anything else?

how do you say aloud -when for instance reading aloud an equation’s terms- something like "15⁴"? do you say "fifteen’s fourth"? (in French we say "quinze (à la) puissance quatre")

Maybe it would be possible to rephrase some sentences of the article in order to provide several different syntaxical contexts, and give satisfaction to the curiosity of non-English-speakers.

Thanks in advance if anyone can figure this out. --Sophievm (talk) 18:41, 24 November 2012 (UTC)[reply]

Formatting[edit]

In my opinion, inline < math> tags in sentences rarely work well. I propose replacing:

if a number ends in 5 its fourth power ends in $25$ (in fact in $0625$ )

with

if a number ends in $5$ , its fourth power ends in $25$ (in fact, in $0625$ ). — Arthur Rubin (talk) 16:25, 28 November 2019 (UTC)[reply]

Senary[edit]

The section on last digits in senary are somewhat interesting and accurate, but senary is not used. Perhaps a section on duodecimal might be added? — Arthur Rubin (talk) 16:27, 28 November 2019 (UTC)[reply]

Is there something special about base-6 that is not shared by other bases except 10? If not I think it should be deleted. Base-10 is only interesting because it's what humans use.Spitzak (talk) 00:12, 25 August 2020 (UTC)[reply]
