Write the following as an interval: $\{ x : x \in R, -4 < x \le 6 \}$

Let $a, b, c$ be real numbers. $A$ set formed with $a, b, c$ whose order of occurrence is preassigned is called:

What universal set $(U)$ would you propose for each of the following:
The set of isosceles triangles

Set $A$ has $m$ elements and Set $B$ has $n$ elements. If the total number of subsets of $A$ is $112$ more than the total number of subsets of $B$,then the value of $m \times n$ is

Prove that for any sets $A$ and $B$,$A \cap (A \cup B) = A$.

If $n(A) = 4$,$n(B) = 3$,and $n(A \times B \times C) = 24$,then find $n(C)$.
