Answer :
This is neither a permutation nor a combination.
How to solve the question
When we say area code, we can assume that we are talking about the 7 digit codes of a phone number that are possibly added to the particular code of an area
If this is the situation, given the 10 ways we can select the 7 digits. But this is not a combination given that the groups do not have the same elements. It is not also q permutation because we are not choosing arrangements of the 10 numbers.
To solve this we would have 10 values to the power of 7 which is
10^7
