State whether given pairs of terms are like or unlike terms.
Terms which are having the same variables that are raised to the same power are called the like terms. They may differ in their numerical coefficient.
Whereas the terms which do not have the same variables are unlike terms.
The given pairs of terms are
The term has no variable
and the term has no variable
Since the given pairs of terms have no terms.
Hence, the given pairs of terms are like terms
