On Mathematical Set

Question 1 : if Q = ( All perfect Square less than 20 ) &
                     P =  ( All Odd numbers from 1-10 )

Find i . Q n P
       ii.  Q u P
      iii. ( P u Q ) n


Question 2: If U = ( Whole numbers less than 50 but greater than 20 )

          Find:     X  = ( Perfect Square )
                       Y  = ( Factors of 12  )
                       Z  = ( Prime Numbers )

Urgent help plz 

are u in an exam hall or what? this is the fastest reply I can give you , based on your buzzing me , i was in a meeting ,

I hope to be back soon , hope someone can help with the formular/answer for no3

perfect square 0, 1, 4, 9, 16, = Q

Odd numbers 1, 3, 5. 7 9 = P

Whole numbers

1, QuP = 0,1,3, 4, 5, 7, 9, 16
2, QnP = 1,9
3, ( P u Q ) n = ?

21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31
32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42
43, 44, 45, 46, 47, 48, 49

x = 25, 36, 49
y = none = factors of 12 are 1,2,3,4,6,and 12
z = 23, 29, 31, 37, 41, 43, 47

I hope am right , confirm this and lets pray am right, you too read your book ooo

(PuQ)n ?=? (an incomplete mathematical statement). confirm the right expression. it either (PuQ)nP or (PuQ)nQ or (PuQ)'

do find out.

he got thru to me via messenger, tried reaching him to confirm formula since, but no response, so I posted what I believe is the solution on the forum for him to see/use pending hearing from him.

u did a gud work. nice approach. he should confirm the last mathematical expression.

I hope am right , confirm this and lets pray am right, you too read your book ooo[/quote]Thanks dude, i appreciate your effort. I'm not in a exam hall just only trying to confirm if my answers are correct.

Now to your answers, mark in bold.

e.g 1, QuP = 0,1,3, 4, 5, 7, 9, 16

Is zero a perfect square? my answer was Q u P = ( 1,3,4,5,7,9,16 )

3, ( P u Q ) n = ? sorry the question is

( P u Q ) n ( ) Empty set.

So its  ( 1,3,4,5,6,7,9,16 ) n  ( ) = ( )
therefore its a null set.

well as for other you're perfectly correct.

Thanks once again.

Hey dude, its already confirm wow i'm impressed to have one on one conservation with the mathematicians in the house.
thanks guy.

saw ur offlines,

0 is debatable as a perfect square, just like -ve whole numbers, lets leave that to the theorians*

Just to be confusing, some people say that whole numbers can also be negative, so that would make them exactly the same as integers. And sometimes people say that zero is "NOT" a whole number. So there you go, not everyone agrees on a simple thing!
