The answer is integer

X=+-6

i'm pretty sure it's neither natural nor irrational. it's ineteger because x²=36 -> x=-6 or x=6 so you can eliminate choice a and c

It can't be Natural, due to the presence of -6
anonymous
  • anonymous
so the right answer is b
anonymous
  • anonymous
It can't be whole due to the same reason
anonymous
  • anonymous
You can call it rational, but integer is a better option
anonymous
  • anonymous
So the answer having both rational and integer is the right one
anonymous
  • anonymous
b or c ? hmm . . .
anonymous
  • anonymous
is it whoLe ?
anonymous
  • anonymous
No not whole
anonymous
  • anonymous
Whole means 0,1,2,3......................
anonymous
  • anonymous
There is no negative in whole
anonymous
  • anonymous
the answer is b riqht ? cuss its rationaL ?
anonymous
  • anonymous
yes

You can solve that equation in any of those categories, but irrational makes no sense as there are constants (2 and 36) in the equation, that are not irrational. All the others are ok. Of course you will get sometimes more solutions and sometimes less. But the equation itself does not tell you which category you should take. And you could always define a bigger category with still more solutions. (For example you have a solution in ℝ^2: \[\begin{pmatrix}5\\\sqrt{11}\end{pmatrix}^2 =\begin{pmatrix}5\\\sqrt{11}\end{pmatrix}\cdot\begin{pmatrix}5\\\sqrt{11}\end{pmatrix} = 36\] Oh and what your the difference between whole and integer numbers? So why is the answer b and not c?

Answer is c because \[Z\in Q\]
nikvist

Correction \[Z\subset Q\]

yes i think you're right i googled about whole number and it's almost the same as integer so the right answer is c
