In thermodynamics limit, does function of many mean values(of some physical quantities) equal mean value of the function of the values?

The thermodynamic limit refers to the theoretical concept of taking a system to an infinitely large size. In statistical mechanics, this limit is used to study the behavior of a system with a large number of particles or degrees of freedom.
The thermodynamic limit is important because it allows us to make predictions about the behavior of a system at the macroscopic level. By taking the limit of a large number of particles, we can eliminate the effects of fluctuations and obtain more accurate mean values.
In statistical mechanics, the thermodynamic limit is used to calculate the average properties of a system, such as energy, temperature, and pressure. This is done by taking the limit of a large number of particles and using statistical methods to calculate the mean values of these properties.
The mean values calculated in the thermodynamic limit are important because they represent the average behavior of a system at the macroscopic level. They allow us to make predictions about the system's behavior and understand its thermodynamic properties.
The thermodynamic limit can be applied to most systems, but there are some exceptions. For example, systems with long-range interactions or systems that are not in equilibrium may not behave as expected in the thermodynamic limit. In these cases, other methods must be used to calculate mean values.
