Unlike terms.
like terms
They are not. Exponents, powers and indices are terms used for the same thing.
It depends on whether you are working with variables. You cannot add terms with variables that have unlike exponents.

are known as like terms.
These terms are called like terms.For example: x and 2x are like terms.But: x3 and 4x2 are not like termsbecause although the variables are the same, the exponents are different.
You can't. You can only subtract like terms. Like terms must have exactly the same variables and exponents on the variables.
