Answer:
It depends. See below.
Step-by-step explanation:
Consider the numbers that lie between [tex]11^2[/tex] and [tex]12^2[/tex] as [tex]x[/tex]
If [tex]x \in \mathbb{R}[/tex], there are infinity numbers between 121 and 144.
If [tex]x \in \mathbb{Z}[/tex] for [tex]121<x<144[/tex] there are 23 integers numbers between them.
