Write the following intervals in set-builder form :

$\left( {6,12} \right]$

Examine whether the following statements are true or false :

$\{a\} \subset\{a, b, c\}$

Write the following sets in the set-builder form :

${\rm{\{ 2,4,8,16,32\} }}$

In the following state whether $A=B$ or not :

$A=\{4,8,12,16\} ; B=\{8,4,16,18\}$

Are the following pair of sets equal ? Give reasons.

$A = \{ 2,3\} ,\quad \,\,\,B = \{ x:x$ is solution of ${x^2} + 5x + 6 = 0\} $

Make correct statements by filling in the symbols $\subset$ or $ \not\subset $ in the blank spaces:

$\{ x:x$ is an even natural mumber $\}  \ldots \{ x:x$ is an integer $\} $
