This looks like 2 or 3 totally unrelated questions to me.

Pentagon?     triangle?      

Is this a serious question - Am I missing something ?

Thanks Geno and Bertie,

I have always found this really confusing Bertie.  I don't think that I ever knew the rule.   

I am repeating what you said because I want to cement it into my head.

$$\\(A^3)^2=A^3*A^3=A^6\\\\
but\\\\$$

A^3^2  =   $$=A^{(3^2)}=A^9$$

NOW I have discovered a new (LaTex) dilema.  

  How do I write  A^3^2 in latex without any brackets ? This it what I get.    $$A^3^2$$   

 The second caret (hat)  is ignored.     

I expect that  the wording of this question is very poor.

107 people are going.   2/3 are going

that means that 107   IS   2/3

so

1/3 would be half that much  =  1/2   of  107 = 53.5 children.

NOW,   unless some poor child got cut in half with a sharp axe, this is impossible!

That I why MathsGod has got a 1 after his name.  :)

Sorry Badinage

You can write to admin but you are not likely to hear back.  When people lose passwords they usually have to take a new name.

FTJ means "For the Juniors"

CPhill did it the same as us - he just made a little error when he simplified his fraction :)

Chris, you made a little mistake when you simplified your fraction. 

Hi Mellie

Oh yes I saw CPhill answer it too but that was AFTER I made my comment.

I must have got it confused with a similar question. 

Sorry anon :)
