Mehek (mehek14):
rational numbers can be written in fraction form
Mehek (mehek14):
so which one can you put there automatically?
OpenStudy (michele_laino):
hint:
\[\sqrt 2 \] is an irrational number

Pi is irrational
OpenStudy (michele_laino):
ok!
Mehek (mehek14):
yes so that would go in the irrational row
Mehek (mehek14):
radical 90?
OpenStudy (anonymous):
\[\frac{ 2 }{ \pi }\] is rational

OpenStudy (michele_laino):
no, since pi is irrational
OpenStudy (anonymous):
Flip it around!
OpenStudy (michele_laino):
is the same answer
Mehek (mehek14):
either way pi is irrational so won't work
OpenStudy (anonymous):
\[\frac{ \pi }{ 2 }\]

OpenStudy (michele_laino):
it is irrational, since pi is irrational
OpenStudy (welshfella):
any square root of a natural number like sqrt 6 for example ( where the number is not a perfect square ) is irrational
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
what do you mean "a perfect square" like no decimal's?
OpenStudy (welshfella):
no i mean like 4 , 9 or 16

9 = 3^2
OpenStudy (welshfella):
25,36 etc
OpenStudy (anonymous):
o...kkk...
OpenStudy (welshfella):
so sqrt 10 would be irrational
OpenStudy (welshfella):
or radical 10 as you say in the US
