B) an irrational number
C) a whole number
D) a radical

Answer 1

what do you think?

Answer 2

I believe either an integer or irrational

Answer 3

\[Q=\left\{ \frac{ a }{ b }|a,b \in Z ,b \neq0\right\}\]
if you put b=1 then all the integers produce from Q ...
so if a number is not rational ,it can't be integer too
\\[Q=\left\{ \frac{ a }{ b }|a,b \in Z ,b \neq0\right\},b=1 \\Q=\left\{ \frac{ a }{1 }|a \in Z \right\}=Z \to Z \subset Q\][Q=\left\{ \frac{ a }{ b }|a,b \in Z ,b \neq0\right\}\]
