Explain why
constant terms expressed as different rational
number types can be combined.

Following are the solution to the given question:

Constants, as the name implies, remain constant, which means that their value never changes.For example, 2 is always 2 and 9.4 is always 9.4, and variable values, on the other hand, can vary. Considering the variable 2x as an example.When and when , hence the value of varies depending on what is.We can't combine constants and variables and they're not the same item; one can change while another can't, and you can't join terms that are not the same.
