Important Math Question

[Boomwebsearch]

Which one of these numbers is not like the others, and explain why that number is not like the others in the set (view attachment to see the number set that I am referring to) ?   I am asking this off-topic question to see if anyone knows the answer and can help me by letting me know. I am trying to review some mathematics concepts that I learned a long time ago.

It's 63. The other numbers are all perfect squares.

 

I.e.

 

25 = 5^2

16 = 4^2

 

Etc...

[Wolther]

16 is the only even number, the rest are odd

63.

 

The rest are squared numbers(25 = 5, 16 = 4, 49 = 7, 81 = 9) and that one isn't.

Wrong section, but the answer is 63. The other numbers are perfect squares

5 * 5 = 25

4 * 4 = 16, etc

Wow, that's also correct. This is a bad question

I realize now that this question can have more than one answer now (although I found the answer that I was especially looking for).

Not really a bad question since it forces you to look for all possibilities which is what math is meant to teach.

If it was meant to have one answer, it's a bad question. @Boomwebsearchconfirmed it can have multiple answers though so it's fine.

49. It's the only number where the sum of the digits isn't repeated.

 

16. It's the only even number.

 

63. It's the only number that isn't a perfect square.

 

81. It's the only number where the sum of the digits is equal to its root.

 

25. It's the only number there the root is also a digit.

Thank you for resolving the problem of this question having multiple answers, it was not really meant to have multiple answers, so I think that if is not really correctly phrased. Although I have found the solution that I was looking for, thanks again.

Also, 25. It's the number Drak3 likes the most on that list.

No, because it's the number of the cups of coffee it takes to make Drak3 give a shit about anything other than gaming, money, hardware, and more money.

Well I had to because apparently saying it in regular replies constitutes spam.

 

I've gotten warning points from one of the new mods and an admin over it.

The real kicker is that The Randomness very kindly asked me to cut back because it derailed a few topics. They didn't say stop, they said do it in moderation.

Now is when you hope the mods don't notice this post.

Spoiler

Because it's technically against forum rules to discuss moderation of users. Which includes yourself

The Randomness did nothing more than ask me a favor. If they were moderating me via the avenue of actual moderation, I'd have gotten a warning about it, even if it didn't have associated warning points.

Yeah but you got warning points from the mod and admins, right. You mentioned that, is what I'm saying constitutes as discussion of moderation
